Live streaming with silverlight 4 - silverlight

Greeting,
Is there a live streaming server for silverlight 4 from Microsoft like Flash Media Server from Adobe that support live streaming for Flash???
I know that there are many open source live streaming server that support silverlight 4 but I did not find some one good as Flash Media Server which support Flash!!!
please tell me if Microsoft has a media server for live streaming or if there is a good open source server for that.
I'm working in building web conference system using silverlight 4 but I have problem with server that all the open source servers I used are really slow.
Thank you,

Microsoft supply a range of services for media including live streaming.
See Windows Media Services.

Difference between IIS Smooth Streaming and Windows media Service

I am looking in to options for windows streaming technologies for streaming live webcam . I am not quite sure pros -cons , price and media format differences between the two . I know that IIS smooth streaming is newer technology and end user has to install silver light plugin to load video . What are other major differences ?
I've found there's quite a bit of confusing information out there due to similar terminology being used and regular releases making even slightly old blog posts out of date.
I assume your question is around "Windows Media Services" and IIS Smooth Streaming
Windows Media Services is a standalone update for Server 2008 (I don't believe its available for Server 2012). On installation you use the Server Manager to add WMS as a new server role. WMS provides for on-demand streaming and live streaming, I dont believe it provides for adaptive bitrate streaming
IIS Smooth Streaming is available in IIS7 via this standalone update IIS7 Media Services 4.1. It is available in IIS8/Server 2012 without any additional download.
IIS Smooth streaming is Microsoft's product name for 'on-demand' smooth streaming.
This is a good blog post explaining IIS smooth streaming.
Pricing - they are both free, assuming you already have the OS licence.

Developing GIS application for windows phone 7 and 8

I am planing to start a GIS application for windows phone (7 and 8) and I have some important questions. Any idea will be appreciated!
1- Database Engine for WinPhone. Is SQLServer Compact the only option for database engine? Is there an alternative?
2- Does SQLServer Compact (or its alternative) support Spatial data?
3- Is there any libraries suitable for works like processing geo-spatial data? Rendering such data?...
SQL Server Compact is the built-in database for Windows Phone. However, if you can find other C#-based databases, they can probably be made to work.
I would expect any GIS library to be commercial. See for example Map Suite which is a Windows Phone GIS component.
You might be able to use some of the code from http://sharpmap.codeplex.com/ - but it targets .NET4.0 rather than Windows Phone.

Streaming a video to multiple WPF clients

I need to stream a file from my server to several clients. I'm not sure which approach to take. I found Windows Media Services but all posts I read are three years old, and all examples are in C++. The content also primarily relates to Windows Server 2003 and/or Windows Media Player 9.
Is this the approach for streaming rich content to WPF clients? Can it really be so, that I cannot leverage the strengths of WPF, but I am forced to interact with DirectShow?
I noticed that my Windows Media Player 12 has some features about streaming content to other plaers, could this be leveraged? It seems like a nice approach that I don't have to go all in with Media Server/services.
What is the approach to this using WPF? Say I want to make 10 clients simultaneous stream the same file across the Internet - or "subscribe" to the same broadcast...
It seems like I have to use the RTSP protocol and Windows Media Server.

Out of browser silverlight 4 application with local database that will run and install on windows or mac?

I am researching using silverlight 4 to develop a desktop application that can be installed from a browser window, now the tricky part is that I want a lightweight database embedded into the application. The database should install with the rest of the application and it should ideally work on both windows and mac systems. Originally I was thinking sqlite would be suitable for this but I have learned that it is not compatible with silverlight. Does anyone know of a solution for this?
There are some available silverlight databases such as:
siaqodb - uses LINQ, available for WP7 - commercial.
effiproz - available for WP7 - commercial.
Perst - open source.
These utilizes silverlight local storage, comes with their own database engine.
There is also Ninja Database Pro that works for Silverlight and Windows Phone 7:

Nowadays SQL Lite is a viable option for SL4 / SL5.
You could also team that up with DevArt LinqConnect product (http://www.devart.com/linqconnect/) that is an EF / Linq-to-SQL like wrapper over SQL Lite.
I've also looked at alternatives Siaqo DB and Ninja DB (as mentioned by others).
While not exactly a database, the upcoming release of the Sync Framework will support offline caching for Silverlight 4 on the desktop/browser, and Silverlight on Windows Phone 7. As Liam Cavanagh mentions in this blog post before TechEd:
I have a TechEd session this week where I will be demonstrating all of this as well as how we will be extending the capabilities of the sync framework for creating offline applications, specifically allowing Silverlight, Windows Phone 7 and even non-MSFT platforms to be used for the clients.

Silverlight/Flash webcast software, similar to Channel 9 PDC 2008

Anyone have recommendations for webcast software, similar to the Silverlight app here: http://channel9.msdn.com/pdc2008/TL57/
I looked at a couple other questions posted here, but I don't want a hosted solution.
The PDC Channel 9 Site is using the player base from http://codeplex.com/SL2VideoPlayer with some of their modifications (which we plan to roll into that project). They have a Windows Media Streaming server back-end delivering the media.
For Flash there is JW FLV Player. Just put the files on your own web server. On CodePlex you can find a Silverlight 2.0 media player.
