i run utorrent on bootcamp. i can never get transmission or azuerus to get fast speeds on osx. but i would choose transmission since it seems to work better than azeurus.
azureus is java based, and is kinda slow compared to others. Unfortunately there isnt anything as good as utorrent for OSX but transmission would be the next best thing to use right now.
What do u mean by "Rogers won't be able to sniff your packets"? like people would hack into your computer, or law enforcements or record labels would spy on you?
