Good question. I think we decided to leave it in since it's
easier to describe in documentation. It's basically a synonym for
ReachableDirAddresses *:80, ReachableORAddresses *:443. Since this step
is automated, it may be smarter just to set each of those directly.

Good point. I guess in Windows-land it should be 443, but in Unix-land
it shouldn't be. Is 8080 popular? What are other good choices that won't
stand out too much?

Eventually I'd like to have an option like "find me a smart port that
isn't already used" and Tor will take it from there, but this involves
some delicate guesswork. And in any case the really hard part is still to
get the user to do port forwarding on his router; maybe we should learn
to play the upnp game at that point too. If anybody here has upnp clue,
please let us know. :)

Actually, as of, the better answer is
"PublishServerDescriptor bridge"

This will cause him to publish his descriptor, privately, just to
Tonga. Eventually we'll have a way to have Tonga export what it knows
so we can tell identity keys to people via various out of band mechanisms.

Hope that helps,
