Why the hell should I use my bandwidth AND pay for the privilage? I get capped at 2mbit for 4 hours if I download more than 1GB during peak time.
It is refreshing to see alternative business models being marketed to the movive/music industry, but these schemes really need to involve the ISP if they are to suceed, especially since as internet usuage increases, availible bandwidth decreases - and they aren't going to upgrade the networks any time soon.
Oh yeah, and if I pay to download a duplicate that only costs the supplier a fraction of wholesale fibre-time, I better be able to keep the copy.
