CVSup over an SSH tunnel

You bet you can.

ssh -2 -N -f -L [localhost port]:[cvsup-server-ip]:[cvsup-server-port] 

For example:

ssh -2 -N -f -L 
user at outside-machine-ip-address

Then you'd simply change your supfile to point to localhost, and 
possibly use the -p [port] option on the command line to change the 
port to 6000.

Good luck.
