FYI OpenSSH has connection sharing in CVS now. It isn't well tested
beyond a couple of platforms: OpenBSD (obviously), Linux and OSX and
parts of it are still subject to change - in particular the protocol
spoken between the "master" ssh connection and its sharing clients.

It certainly won't do anything fancy, like opportunisticly starting up
a connection if one doesn't already exist - but we want to get the guts
of it well tested before we add features (if we ever do). The sort of
thrashing that distcc would likely put it through would be welcome.

It has certainly been useful enough to change the way that I use ssh :)

(hint: set up aliaes for master and client connections in .ssh/config)
