You want WISP competition (co-op business model or not), then lobby the FCC to free up some spectrum for it. Cheap gear is here, spectrum is the scarcity.
So here is the plan- we jam a frequency of a local TV-station, nobody views, who is just sitting on the spectrum for license worth. After proofing for one year and one day, that nobody listened to it and nobody cared- we pronounce that this spectrum is unclaimed and should be returned to the government to be auctioned off.
Under normal circumstances this should not go through legally- but hey, there is booty, there is a government in debt and there are interested parties.
Its the perfect storm and just having legal rights - didn't help the native Americans either, didn't it?
Come to think of it- maybe planning the heist in public was - ill advised.
