Tor is awesome, but many sources state it shouldn't be used for p2p.

I wish Tor would run as a server whenever the "client" portion is loaded; similar to how any other "p2p" application works, once you are connected, you are "sharing" and using the system.

But I think it's more of a trust issue; they don't want just any random person being able to set up a node (i.e: for logging or wahtever....)
