Internode is a bad example, they are the best of the lot in Australia/NZ, as I know from personal experience :)
I suspect how it will work out if it happens in the US is rather more like how Telecom NZ or Vodafone operate (Telecom used to be mainly owned by SBC/AT&T).
Where either you don't have the option of a data block past a certain upper bound, and get shaped to 64kbits for the rest of the month (Vodafone).
Or you have the option to remain full speed but the overage charge is out-of-this-world insane, something like 2c/MB. That's right, per MB. 10GB over cap is $200 added to your bill. Ouch.
