Who Bears The Cost? (Score 2, Interesting)

Let's say I attempt to download some music over a peer-to-peer file-sharing system. One of the keen, young whizkids from the RIAA's l33t anti-theft squad spots me and begins hosing me down with ultra-large packets. Who pays for the bandwidth? The RIAA? Or me? IF I start downloading and leave my computer on over the weekend the RIAA terrorist could, in theory, feed me 10-20 gig of meaningless 'data'. At my cable provider's rates that's AU$1700-3400 (US$850-1700). Since that would instantly bankrupt me, causing my bank to foreclose and me to lose my house, would I have some recourse against the RIAA? Bear in mind that I live in Australia and so this would constitute a violation of even the meagre 'jurisdiction' that the RIAA claims in the US these days...
