In Mono 2.8, the following assemblies and code come from Microsoft:

With Mono 2.8 we are going to default to the .NET 4.0 profile. So from the list above MEF, the DLR, OData and MVC2 become first class citizens in Mono-land, no longer third-party packages that you needed to install.

Update: as of July 17th 2010, the DLR, IronPython and IronRuby changed their licenses from MS-PL to Apache2.
