If you use a hostname, it does a reverse DNS lookup to verify the
identity -- if that's not suitable you can change the hostname to an ip

No problem offering the ssh.  It's not horrible to setup if you know
what you're doing, it's just a bit more work.

I'd *really* like to see the changes pushed ASAP.  For one thing, we're
not relying on the correct usage and timing of a remote cron job to make
sure our mirrors are up-to-date.  It gives us a bit more control of
content flow.

If you did set up primary and secondary mirrors, how would you decide
which mirrors would be which?  Based on bandwidth? Location?
