Just hit me that you could use an anonymous proxy to defeat the ip address mechanism if necessary. If cookies alone doesn't work, check out something like http://www.guardster.com/ or any of other thousands of free proxy server sites. Some you can just surf thru, some you have to configure your browser to use the proxy address. "Transparent" proxies will not rewrite the source address, but any other proxy config will. Let us know what you find out after eliminating each criteria.....
