If simply connecting over a certain port was the answer I could have setup SSH on port 433 and been done without even that. Though I'm happy to be told I missed something obvious, in case I have the same need again in future.
Also just thinking about the SSH connection forgets the "want it to work on any machine" extra requirement I had. Being able to run an SSH client directly _at all_ was a concern.
