Office ribbon for WPF 4.0 - wpf

Question

It is rumoured that WPF 4.0 would deliver us an out-of-the-box Office Ribbon.
A new WPF Ribbon Control will be
available for download shortly after
the release of WPF 4. [1]
Now my internet and MSDN search turned out to be fruitless, and as far as I know, it would be release after the .NET 4.0 framework would launch. My search lead me to the Office plugin ribbon controls and the CTP prereleased before the release of .net 4.0 with a limited featureset.
So my question is: does anyone know if and when Microsoft will release this Office Ribbon with the framework? Or if they don't a nice press note saying that they ditched the project.
Also if anyone has experience with the Ribbon I'm talking about, will this Ribbon work in a partial trusted environment?
My thanks will be ever lasting! ;)

This may be old news to you now but there wasn't a selected answer so here you go:

You can download the source, examples, and assemblies for including a ribbon. The documentation can be found on MSDN at http://msdn.microsoft.com/en-us/library/microsoft.windows.controls.ribbon.aspx.
Simple example from a project that includes the 4.0 version of the RibbonControlsLibrary.dll
<Window x:Class="WpfRibbonApplication1.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:ribbon="clr-namespace:Microsoft.Windows.Controls.Ribbon;assembly=RibbonControlsLibrary"
Title="MainWindow"
x:Name="RibbonWindow"
Width="640" Height="480">
<Grid x:Name="LayoutRoot">
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<ribbon:Ribbon x:Name="Ribbon" Title="Ribbon Title">
<ribbon:Ribbon.HelpPaneContent>
<ribbon:RibbonButton SmallImageSource="Icon.ico" />
</ribbon:Ribbon.HelpPaneContent>
<ribbon:Ribbon.QuickAccessToolBar>
<ribbon:RibbonQuickAccessToolBar >
<ribbon:RibbonButton x:Name="QATButton1"
SmallImageSource="Icon.ico" />
<ribbon:RibbonButton x:Name="QATButton2"
SmallImageSource="Icon.ico" />
</ribbon:RibbonQuickAccessToolBar>
</ribbon:Ribbon.QuickAccessToolBar>
<ribbon:Ribbon.ApplicationMenu>
<ribbon:RibbonApplicationMenu SmallImageSource="Icon.ico">
<ribbon:RibbonApplicationMenuItem Header="Hello _Ribbon"
x:Name="MenuItem1"
ImageSource="Icon.ico"/>
</ribbon:RibbonApplicationMenu>
</ribbon:Ribbon.ApplicationMenu>
<ribbon:RibbonTab x:Name="HomeTab"
Header="Home">
<ribbon:RibbonGroup x:Name="Group1"
Header="Group1">
<ribbon:RibbonButton x:Name="Button1"
LargeImageSource="Icon.ico"
Label="Button1" />
<ribbon:RibbonButton x:Name="Button2"
SmallImageSource="Icon.ico"
Label="Button2" />
<ribbon:RibbonButton x:Name="Button3"
SmallImageSource="Icon.ico"
Label="Button3" />
<ribbon:RibbonButton x:Name="Button4"
SmallImageSource="Icon.ico"
Label="Button4" />
</ribbon:RibbonGroup>
</ribbon:RibbonTab>
</ribbon:Ribbon>
</Grid>
</Window>

Have you seen the WPF 3.5 ribbon?

Answer 3

It should work in partial trust unless they make a huge mistake :). Things not allowed in partial trust are:
Connecting directly to SQL
Reflection
a few other things
Shouldn't be doing that sort of thing in a UserControl (even if it is a bit fancy...)
