blocks all outbound ports except 80 and 443. So I couldn't do alot
You should tunnel everything through ssh or vpn when on a public network, anyway, so having a server or router you can ssh into on 443 and use for tunneling is a must for mobile work since it solves the port blocking problem, too.
It takes a remarkably crappy security gateway to allow this trick to work; you can't really do it through a Blue Coat or PIX/ASA, because they're doing full proxy for HTTP/HTTPS and they cut off long-lived connections.
