I think a better approach than tor that we'll see in the next few years will be a readOnly private "tor" box that you can hide on any network with open wifi. The Raspberry Pi is the perfect platform for this. Such a box would be running tor and only visible on the Tor network. You'd SSH into it over for and then have your own private exit node. All you need to do is drop a couple of these in places where there is power you can piggyback off and a wifi signal you can piggyback off or a network you can patch into.
