What's wrong with using google code for the subversion repository (among other things)? Using Git would definitely be another option if people are comfortable using it (or willing to learn, but I think the same is to be said for SVN and CVS), but I quite like the centralised nature of SVN over Git (but that's just me).

As for the business about the lack of a project leader, hopefully someone can step up to the plate sooner or later. However, it's hardly an impossibility to get things underway just now without a single person making all of the final decisions. Just someone, anyone, come to a decision (after absorbing what's been said here) about one little aspect of the project and we can tick it off (even if we do come back and review it later). As the saying goes, pull your finger out!

I'll be back home in a wee bit over a week and am not afraid to make some 'final' decisions then. :)
