Why don't you guys have a look at the notions in Xanadu- I think they're
worth considering in this case.  Implementation is another issue.  But
you can start by going to http://www.xanadu.com .

In particular, start looking for information about Xanadu's "Virtuality",
and compare that with what you may want for a source code management system-
especially when you want to share on a planetary scale.  If nothing else,
at least Project Xanadu has spent a lot of time thinking about this topic.
