[Zope] Wildcard DNS with zope?

Hi Does anyone know how to do wildcard DNS/subdomains with Zope? I want to be able to have something like anydomain.mydomain.com where anydomain is anything the user enters at anytime and doesn't demand a DNS entry or directory is set-up. I'd like to create a service like wasarrested.com but less rude :-) (i.e. try http://www.zope.developer.wasarrested.com/hack ) - it takes the variables from the subdomain and generates an article. Once set-up I'd post the code on zope.org Cheers, Duane
