First try if you can use proxies... www.proxytastic.com ... www.proxy.org
What is this free web proxy thing all about? - A web(based) proxy allows you to surf the world wide web safely and anonymously. Also this allows you to bypass company/school firewalls and proxies, allowing you to browse your favourite blocked websites, such as myspace.com, bebo.com, facebook.com and orkut.com at work or school, while your friends and colleagues can't. Try it! It's free, reliable and easy!
The only problem is that if the free proxy sites are blocked - also proxy sites lag and tend to have many ads. (Uh I dunno if I should be posting this, I think it's legal...?) [all it does is disguise your IP]
