Tor as a client also needs support for inbound binds for some apps, at
least at the single per port level when interacting with internet at the far
end. OpenVPN might, or could be extended to arbitrate those port
binding requests.
Hidden services do support such binds in hs-to-hs mode, at least
statically.
