[ale] Getting around blocking software

[ryan at jimmyether.com (Ryan Williams)]

Can anyone suggest a linux alternative to Circumventor type software?

I'm setting up a linux box at home and wanted to give my wife a way to  
get around some of the blocking software at her work. For some odd  
reason, they have inexplicably blocked some truly harmless sites she  
wants to view on her down time. We've tried just using the IP for these  
sites or various anonymous proxies, but no joy. Any suggestions are  
welcome.

Thanks!
