He's referring to the HTTP CONNECT method, which can tunnel arbitrary 
TCP connections, not just HTTP. The IETF draft for this is titled 
"Tunneling TCP based protocols through Web proxy servers".

AFAIK, there are no Python modules which support that. The protocol 
itself is fairly simply though, so it shouldn't be too hard to write 
your own wrapper or proxy for the client side. Things get a little more 
complicated if you have to authenticate with the proxy first.
