Hosting a site on my iBook.

Sure. IIRC, every Mac comes with a copy of Apache (and if not you can download it for free). Here's an article about getting it set up (it's for OSX 10.2, so it's a bit dated but it should all still apply to 10.4):

Just remember that it'll only work as long as the iBook is connected to the Internet on a known/knowable IP and not sleeping/off.

If you want to do it for free, I recommend either DynDNS or No-IP.

These won't give you clean domain names for free, only subdomains, but I believe No-IP has a paid option for domain names.

I use the free DynDNS with my Linksys WRT54G (it has an option in the prefs to setup DynDNS with my dynamic IP), and I love it! Works great.

I already have a domain registered. I was wondering if I can use that.

Odds are, no. You'd need at least a static IP address. Do you have one?

Then you won't be able to use a registered domain name, as that would require a static IP for the Domain Name Servers to use. Unless, of course, someone more knowledgeable than me can come up with a solution.

Edit: FWIW, ASO will host you for $25/year. Pretty decent if your bandwidth requirements are low.
