I repair computers. Occasionally (less than once a month) I'm forced to work on a computer without my equipment and no admin privileges. I use bittorent to download linux distributions, I frequently get better download speeds on computers with slower connections. I need a torrent client that I can downloaded and run off a flash drive (someone elses, not mine) without needing any kind of admin privileges. I refuse to plug my jump drive into clients computers, so I need to be able to download and install the program to a jump drive without using an admin password.
