ssh multiplexing

Does anyone use OpenSSH 3.9+'s multiplexing (the ControlMaster and ControlPath options)? How have you made it painless enough to replace ssh-agent?

It seems to me that in an ideal world, rather than having the key exchange, etc. happen once per process, I'd rather be able to indicate "open a secure connection to this host" (which wouldn't bring up a shell) and then be able to open many shells, port forwardings, and copies as I'd like over that connection without reauthenticating. But as I understand these options you need to specify one connection as a sort of master and then explicitly tell the rest to use the master connection...
