I think that this really blocks Tor. Tor currently uses IP addresses  
to connect to other nodes, if you're behind a proxy that disallows  
such connections, Tor will be effectively blocked. I see the possible  
solution of a proxy chain or a tunnel to a server without using it's  
IP address directly.

Have you tried such an approach?
