El_Caz: Still, this kind of technology can only improve. Greater broadband and better video quality is not so far fetched. Plus, you don't really get to install any byte from the game on your computer. Anti-piracy at it's greatest.
I wonder how well this would work if they simply charged more as a subscriber service (say, $20.00 a month) and you DON't get to buy the games, they're just there, included with the service. Play anything you want for a monthly fee. Stop paying, stop playing, return anytime.
The technology will improve but it's the Onlive pricing AND the ISP pricing that matter the most. Bandwith requirements only increase they don't decrease and with ISP's being ever more stingy doesn't help.
As for "piracy"....
Whenever you shift the "piracy" away from physical\digital media to a server-only model then the "piracy" then moves to hacked accounts\stolen credit cards and such. You can never get away from "piracy". You'll just move it to a different method and/or lose your potential customers.
