I agree with ppoppin. It depends on your ISP if you get capped or not. As far as if they should do it or not, I'm not so sure. If it is having a noticeable negative affect on the ISP's network speeds, then by all means do it. But I wonder if it really does affect it as much as they would have us believe. Perhaps in a large city it is an issue, but in a more rural setting it doesn't matter? I'm on COGECO in the Niagara Peninsula in Canada, and I've learned (from forums) that they throttle torrent speeds in a nearby city, but I live out in the countryside 20 minutes away from said city (very fortunate to have cable!) and have never been throttled myself, having upload speeds around 120kb/s.
