Thanks for the explanation.

My question arose because Apple's Remote Desktop uses UDP (well, a
combination of UDP and TCP) and a colleague needed to securely tunnel
it into his client site.  He typically uses SSH for other access to
the client.  We'll end up setting a VPN tunnel but that seems
overkill.

I vote to amend the standard to allow UPD port forwarding.  :-)
