Well, in the past two weeks the number of nodes and available network
bandwidth has fallen due to a combination of stability and
blacklisting issues.  http://www.noreply.org/tor-running-routers/

I've been wondering for some time if it might be possible to attempt
more intelligent node selection when building circuits. I've noticed
that connection setup time has quite a bit of variance to it, and I'm
guessing that this is due to occasional selection of heavily loaded
nodes. Would it be possible to include a statistic in the directory
for node load? Maybe something as simple as using the ratio of a
throughput stat to expected bandwidth as the node selection criteria
instead of uptime?

How quickly can the directory be updated? Would this introduce cyclic
load problems, or perhaps other security concerns?
