Come to think of it, couldn't you guys just use the iPhone web app now? I mean, Safari works on computers just like on the iPhone. The current interface leaves something to be desired on a PC, but that would be a lot easier to fix than adding syncing functions.

Why not just designate one of your machines the central OF repository, turn on the web server on that machine, and access it from everywhere else? No syncing required. Then you could use it not only on your own machines, but on any public terminals or work machines (or even *shudder* windows machines) that you happen to be using.

I really see the Ruby on Rails functionality fixing these problems with a lot less effort than .mac (and probably better results).
