250GB and more.....

Sorry, but if you don't want them to leech off you, stop sharing your music collection online. Of course, if you are actually referring to the financial cost, (illegal) music downloaders actually were the reason that paid online downloads were made available. These subsequently have made it cheaper to buy your favourite songs as you can now download them instead of forking out for a CD. So in essence, they've actually saved you money.
I don't download anything these days, with the exception of PS3 demos and games from the Playstation Store. Even that though can swallow 10-20GB of bandwidth in a good month.
250GB seems like a very nice cap though. A normal user, watching internet TV and films, browsing, downloading LEGAL demos and software would be quite hard pushed to hit that limit, certainly on a regular basis.
Another poster asked why they should have to pay the same as somebody else who uses 10x the bandwidth that they do. The answer to that is simple...ISP's have long and often advertised "unlimited" internet. If you choose NOT to take advantage of this "unlimited" connection then whose fault is that? The fact that the ISP's can't actually support what they have advertised is not the fault of your heavy-downloading neighbour.
I'm all for appropriate caps or metering, as long as the numbers are fair and it does not breach the conditions of any current contracts.
