hm as someone who always has a few servers up in the cloud i found the idea exotic at first. especially since you dont need github, any ssh connection between two computers will do. but thats not always easy and the more i think about it, git over xmpp sounds like a cool idea. but still, in the end one can just email or dropbox the whole zipped repo. and git patches and whatnot.
I think, using git for what it traditionally is used for, there probably isn't much demand for XMPP. Joey's thing seems to be expanding the horizons of what we can use git for though. Building cooler toys out of git, not just with it.
