There won't be any viable option when the few major backbone providers put in the toll booths. Everybody's traffic goes across them, so they basically get to hold the American Internet hostage.
How much of this is gray? Seems to me there is an awful lot of internet connectivity NOT in the hands of the 'few major backbone providers,' and I don't know that 'everybody's traffic' goes through them at all. The internet was built to avoid traffic jams at tollbooths, and what will happen is that providers who want to charge sites for speedy upload will suddenly become less likely to provide service to those sites by users, so these providers will also be less attractive to users.
