OO...this could be very useful to me. What would I have to do to use my iBook from school to connect to my Mac mini at home? The Mac mini is on an Airport express wireless network and at school I would be on a wireless network as well.
To sort of append to what

You need a known IP address to connect to. The easiest way I've found to do this (unless you have a static IP at home) is to go somewhere like DynDNS.org and get a free dynamic DNS setup. Then, on your home router, make sure the VNC traffic is routed to your Mac. It's usually on ports 5900-59xx, where xx rarely exceeds 01 or 02. Also, the Mac that you want to get to should have networking set up to use a manual IP address, or DHCP with a manual address - you want to be able to tell your router where you want to route the VNC traffic to, and you want it to always be the same place (your Mac at home).
So, say you get mymacmini.homeip.net as an address from DnDNS.org. That'll take you to your house router. Then, suppose you set your mini up as 192.168.1.101. Go to your router, and route all traffic on ports 5900-5910 (say) to 192.168.1.101.
Then, on the mini, enable VNC by going into System Preferences...->Sharing and turning on "Apple Remote Desktop". You'll need to supply a password in the settings.
On your iBook, install CotVNC, and then tell it to go to (say) mymacmini.homeip.net, give it the password to use, and you should be all set - if the wireless network you're on doesn't block those ports.
You should be able to test this setup at home, first my using the mini's internal IP (say, 192.168.1.101) and then with the external IP.
