Your Web Based Desktop

This isn't about CLUSTER but about our process. We're keeping all our group documents on Google Docs which has so far worked pretty well (minus a couple feature desires) because we all always have internet... And then I went home for the night to see my Parents the Luddites, after 11:00 (when dad heads to bed) the wireless goes off. Three aye em rolls around and lo: no internet, no docs, no ability to work. Of course I peek around the neighborhood for other available wireless and (of course) no dice. Thus: I can't commit to web based computing until reliable interwebs blanket the burbs. It would be really *really* nice if there were slick source control with easy desktop check in/pull down...
