To be honest most "middle boxes" I've seen rejecting UDP were just... web proxies and thus not letting *anything* go through.

Of course any intermediate kind of network crippling is possible in theory.

Are you sure? I suspect most firewalls, load-balancers, and other middle boxes which do port forwarding or filtering are filtering by protocol, so they will filter out UDP if only the TCP port is open/forwarded.
