And what about the growing issue of ISPs capping bandwidth-per-month usage?

Wouldn't the best solution be to allow ISPs to cache the bulk of game data? I'd imagine it would work like this, you dowload a few megabytes from Steam or whatever and that initiates the download of a multi-gigabyte signed and encrypted file from you ISP. Everyone wins, less bandwidth for the game company, the ISP isn't using bandwidth outside their network, and the enduser gets the fastest download possible.
