Good point, and one I hadn't thought of. I'll probably pick up an extra WRT54G once I have some extra cash. Right now, I'm completely broke - moving into a new house and getting all roomates to get new jobs takes time - and I doubt that our wireless router is any more likely to get traffic than the other 3 unlocked ones that are available walking down the street.

I really wish I had the free time to try to organize a wider city wireless network: I'd love to have municipal wireless, even if was just downtown or by Harvard or something. Then I wouldn't feel it quite so neccesary to offer the open wireless in the first place :)
