You don’t have a lot of options. You can’t really outsmart your ISP, even if you find a way to get it connected through a proxy or super encryption, they’ll still know you’re using it. You can sign up with a different company that doesn’t block it. You can look into having your friends download things for you, I suggest buying a portable hard drive in this case to save money on burning DVDs.
Here in Canada we have few options. The two major internet players (at least in Ontario) are Bell and Rogers, DSL and Cable respectively. Rogers has already implemented torrent throttling as well as download and upload limits. Bell also throttles torrents between certain hours (which are, of course, hours THEY define at their whim). The only way I’ve been able to get around these throttles is by signing up with a third party company who buys access from Bell to the DSL lines (the internet is STILL throttled though), and I use the Linksys WRT52G-L router with a different firmware which uses a certain transmission protocol that Bell is not throttling at this time. If they start throttling THIS, well I’ll really have to think outside the box then. It sucks, but until some serious net neutrality laws are implemented, ISPs will continue to run the show.
