For my startup broadbandnow.com we've been emailing every mayor in the US offering free statistics about coverage, fiber penetration, etc in their local area along with how they can bring faster speeds to their area.
So far the campaign is going well, we've emailed almost 300 mayors, but after countless phone calls and email changes with city officials, the disheartening reality is that most cities have 2 options to bring faster interent to their area.
1 - Install their own network
2 - Beg incumbent providers to increase their speed / coverage.
I think it's still a few years out, but I'm forecasting a huge slew of crowd funded or community backed providers entering the market to fill the gaps in coverage. (Our goal is to be a part of that movement)
1- This is all based on what I recall from conversations with EPB higher-ups when I spent a day chatting with them for a school event.
also, if you're really interested, New America Foundation recently published a good study on public broadband options http://www.newamerica.net/sites/newamerica.net/files/policyd...
