It's not a matter of what I propose Andrew (I don't think bittorents should be made illegal, irrespective of how people primarily use them, for the same reasons that you make with banning cars because some people drink drive), it's a matter of what the RIAA and MPAA want. They are 2 very very very powerful organisations, with very long arms of influence within the US administration. Since the US has many trade agreements, with many different countries, and most of these agreements mean adopting US style laws (reason why Australia legally recognises the US DMCA I might add), it'll trickle down to us. There's already talk of ARIA pushing to have it banned. Politicians are pretty stupid as a general rule, and very out of touch with both the real world, and technology I might add, and they're gullible, and on the take from big business as a general rule. 1 + 1 =2, it's quite elementary dear Watson.
And yes, I apologised for my earlier misdemeanour about saying that torrenting was illegal.
