interesting thought : why not start considering the ISPs the same way we consider electricity providers and natural gas providers?
I would expect to see a significant increase in the number of programs available to capture streaming video for viewing later on, as well as programs to queue downloads - as well as an increase in MPAA/RIAA-style lobbying to make it a felony to use such programs.
(These programs would of course be used to take advantage of lower off-peak-hours rates, assuming they would take that route.)
Either way, they'd likely set up their fee schedules so that 90% of their customer base would either see no change in the monthly cost, or else would get a small increase.
And some rhetorical questions:
What happens if your computer starts downloading updates or programs without consulting you?
Do I have to pay for downloads that are interrupted or corrupted due to the ISP's screwup?
Do you have to pay for updates that are fixes for problems that another company caused? ("Oops, we just discovered 87 bugs in this program you bought from us. You must pay your ISP for 850MB of patches to fix our defective product.")
What if a new worm or virus evades your up-to-date antivirus software, and starts uploading and downloading garbage data to and from other infected computers, or just from some central server set up by the malware's writer?
