Another vote for Bazaar, mainly because of simplicity and cross-platform support. If you're developing on a laptop away from the server (or don't want to be tied down to one), a DVCS is the way to go.

At this point, the best thing to do is for Versions (or someone who can get it done a little, um, faster ;-) to support an open plugin architecture and let the 'cool kids' develop their own connections to their favorite VCS tool.
