Re: distribution of per-port traffic across exit nodes

[Ben Wilhelm <zorba@xxxxxxxxxxxxx>]

. . . and, just to throw another wrench into the mix, what happens if 
port B doesn't actually get any traffic? Do routers A and C split it 
evenly, or do they assume port B will get equal traffic, thus sticking A 
with 2/3 of the traffic and C with 1/3?

And, more to the point, is there any way to collect bulk port usage data 
from nodes without destroying anonymity? Because that seems to be the 
ideal solution to this, but not without unfortunate side effects.

(And another question on top of this - should all traffic be considered 
equal?)
