Actually, if he could do the porting, he's way too late to get hired for that. MS started that several years ago, but their biggest supporter (unnamed, and I don't know who it was) pulled the funding and that's why Mono is not an MS group.

Had a couple of friends involved in that when MS was doing it, including my ex-boss who was a mucky-muck in the group. They've all scattered to other groups at MS or have left the company.
