Right.  SSH has an extension mechanism: message types with an
@somedomain.com are "vendor extensions" that do not require IETF
standardization so it'd be relay-udp@$something.  It'd need some kind
of association tracking for UDP host/port pairs to replace the stuff
the kernel does for us with TCP, so it'd probably more complicated to
implement than the existing SOCKS/direct-tcpip support.
