The internet is supposedly everywhere, yet we are all still forced to access it via a small number of centralized ISP companies, with all the obvious problems that entails.
This might just be a unworkable idea but here goes:
What about a DAC that incentivizes sharing your internet connection? I would happily share mine if software was available that made it easy and worth my while.
There has been a proposed project called TorCoin to incentivize running Tor relay nodes. Maybe this could be done in a similar way.
