domaintyper.com clone

I need a clone of [login to view URL] but I only need the whois features. Example: I need a field in which I can enter a domainname and it will lookup for the selected tld's if it is free. The whois servers and test strings must be stored in an mysql db. If the nic supports whois-is service, whois-is must be used to avoid blocking of the webservers ip on the whois service. The visitor must be able to select which domain he wants and add it to an php array, thats all. I've lot more work, so this is also a little test project, please only coders with xp on ajax & fast (running) php coding
