tor and p2p

[eweb101]

The section on Bandwidth and filesharing seems to be dealing with exit 
nodes. What I'm suggesting is that content is contained within the Tor 
network so exit nodes are not used at all.

What I don't know is if the non-exit nodes in the Tor network are 
bandwidth-constrained. If there is extra capacity in the middle or 
entry nodes, P2P may be a good way to fill that capcacity.
