>Actually, please point me to the SSH standard document and section that lists that sshd *must* run on TCP port 22 to be a valid SSH server. 

It doesn't.  It (http://www.ietf.org/internet-drafts/draft-ietf-secsh-transport-18.txt) says
"4.1  Use over TCP/IP

   When used over TCP/IP, the server normally listens for connections on
   port 22.  This port number has been registered with the IANA, and has
   been officially assigned for SSH.
"

Note that it says the server _normally_ listens for connections on port 22.  It does not say MUST or even SHOULD.
