Don't need to. I use a VPN into my server at home (I have broadband at work and at home) so that all traffic is going from my laptop at work, to me server at home and out my home internet connection, and it is encrypted from my laptop at work, to my server at home, so there is no way for them to filter or see what or where I'm going... VERY handy for getting around the filter Cablevision put on the schools internet connection.
