As far as I can see email and irc don't have a bandwidth problem. At
least not to the extent that web browsing does. My suggestion was for
some exit nodes to start only doing http, not "all" exit nodes, and not
even "most" exit nodes.

If there was easily accessible up to date information about what sort of
traffic is going over the Tor network, individual administrators of exit
nodes could make their own decisions about what is most needed.

Ideally, I'd like to be able to tell my tor exit node to aim to make 75% of
it's bandwidth available for http requests, and to only use this
reserved space for other protocols when it's not being taken advantage
of. That sounds complicated though.
