I use hg-git as my git client; I get to use the hg semantics and UI but still talk to, well, github behind the scenes. There are a few rough edges but it works pretty well. But hg-git doesn't talk to the git CLI at all --- there's a Python library which speaks the wire protocol. So it'd be entirely possible to build a git workalike with a traditional DVCS user interface which seamlessly interoperates with git repositories. I wonder if anyone's already done this? ...dammit, I have too many stupid projects on the go as it is.
