If you allow out FTP I will be able to start an SSH connection over port
20 (FTP-Data) and it will look like a binary data transmission on any
network sniff.  In reality I am forwarding a local port to a remote
squid proxy and instructing IE, Netscape or the browser of choice
to proxy through the local port.  Finding a solution to block something
like this (similiar to what you mentioned above) may be difficult...

If you find something, please let me know...
