How about Mono?
===============
-While it would be nice to be able to use dotGit on Mono it is NOT supported at the moment. The main reason behind this is the fact that we're using native Windows API calls to create memory maps because this is not supported by the .NET runtime. Using memory maps drastically improves dotGit's performance and we're not willing to sacrifice this huge performance boost for portability.
-Furthermore Mono is, for the most part, used on \*NIX systems. Obviously, Git support on these OS's is excellent. Using regular Git is the sane choice here.
