Eh.. "sharing" is relative. Essentially the N900 acts as a mobile proxy server. You're just logging into the box with an ssh client (ssh = secure shell, meaning it's encrypted traffic) like PuTTy, setting up a tunnel and then surfing wherever you need to essentially from the location of the phone. So say you want something in the U.S, you would just have a U.S. N900 user create you a temporary account and off you go. Or in France, same thing, etc. If everyone got on the bandwagon, it would be close to impossible to censor anyone.
