Dear Marco,

The issue is somewhat controversial, and as far as I know it's not
discussed in detail anywhere.

Cons:

1. Bittorrent is optimised for bulk transfer.  Tor is designed to be
a low-latency network.  Using high-throughput applications such as
Bittorrent over tor is pointless.  One should instead implement
anonymity in the P2P applications themselves (as Freenet tried, and
failed, to do).

2. Tor currently doesn't include proper fairness algorithms.  Hence,
running a Bittorrent client gives you an unfair share of the available
bandwidth, and kills the latency for the rest of us.

Pros:

1. Tor should be able to deal with Bittorrent.  Running Bittorrent over
tor is what might finally get the tor developers to implement proper
inter-flow fairness.  (Yes, I know, it's a *very* difficult problem.)

2. People do want to run Bittorrent anonymously.   Allowing Bittorrent
on the tor network might bring more interest to tor.


I think that's it.  Take your pick.
