Completely aside from the ethical and censorship-related buzzsaw you're about to run into for posting this (perennial) question, I believe some actual developers on Tor have written a paper about the problems with Bittorrent et al (and I think there's a more specific one than the Why Tor Is Slow[1] paper) but I can't currently find it.  Anybody know?

NB: the above paper is from 2009.
