Other approach exists as well - SecureID on firewall. Login to firewall, authenticate, and have dynamic access list which opens ssh for you (and still keep ssh on port != 22).
Or VPN in, or set up a tunnel of some sort. Have ssh available over the tunneled interface. Yup, lots of options available.
Though, if you have a secure ssh and reasonable control of your passwords it is probably safe to leave it at port 22 rather than resorting to security by obscurity measures like running it on a higher number port or (as at least one webhost does) running it on 443, with some kind of shim listening on that port, intercepting requests to it and redirecting them to apache or sshd as appropriate.
Amen. Now, without any consideration regarding security, obscurity or whatever, I'd say that having an sshd on port 443 somewhere is a good idea if you happen to use a gprs network where all except 'web' ports are filtered (orange.fr comes to mind - at least they used to do that when i was still living in france) - yann
