Dynamic Languages outside of Silverlight

This post is for someone who is familiar with the DLR... hopefully at MS.

I'm looking to use the DLR to run ManagedJScript on the .Net CLR, not in Silverlight (CoreCLR?).

I can do this easily with IronPython and IronRuby since I have their sources along with the DLR (all on codeplex) and none of the libraries actually rely on specific types in the Silverlight core dlls (such as system.dll v2.0.5.0).

Are there any plans to release the ManagedJScript source or at least binaries built against .Net runtime dlls?
