Has anyone heard about Microsoft working on a similar project? The proof of concept last summer seemed to have raised a lot of interest among Microsoft people. I hope they take that route.

Edit : I misread this article. Neiter of the projects i mentioned target webassembly. But CoreRT could one day.

Microsoft has two similar projects:

CoreRT : Which is a managed re-implementation of the CLR allowing for AoT compilation.

LLILC : A LLVM Backend for .NET MSIL. (Stalled)
