Is it possible to get a whois database?
 

I want to launch a service for domainers that will require a database of all current domain names.

It doens't have to be updated constantly, once every 2-3 weeks should suffice.

I also don't need all the whois info, mainly just creation and expiration date.

As far as extensions, would really like to get all of them, but would find just .com .net and .org useful as well.

So, anyone know if it's possible to get such a database? I'd pay a some decent money for this...
