Always have a friend reachable by phone and able to open a ssh access to a special port. When you're are working at a customer HQ with a Windows station, 5 firewalls in front of you and a limited Internet access, that might make your day.

Yeah, if the firewalls allow https over ports other than 443, and don't check what kind of traffic goes over it (real https, or ssh, just a telnet to an open ssh daemon at port 443 will show that it 's an ssh daemon, and the firewall admin can block that host).
That's actually what they do where I work.
So, now it's http://www.anyterm.org that makes my day! A javascript terminal running on the remote host, and you interface with it via https, over port 443 (or any other port at your option). I've password protected the anyterm page, so that the firewall admin cannot check what page it really is.
Why simply not to use stunnel to fake the firewall instead of ssh'ing ?

Give a try to openvpn. It can make an vpn using https protocol. You still needs some friend to run the server, but it's useful.
