I thought FON was doing this worldwide already. You install custom firmware on your router, share your Wifi with the community and then you can use other people's Wifi. They even have a google map with available FON locations. In my town of 100K people they have around 20 FON spots, which is not enough for blanket coverage, but better than nothing.

This situation strikes me as very similar to what happens in financial markets. The whole industry is not creating any value, since they primary occupation is buying paper and then selling it at a higher price. Some may argues, that the traders add efficiency and liquidity to company price formation. Can we apply the same argument to patent trolls?
