If we can decide on how to handle more dynamic ways of dissectors
calling other dissectors, then a plugin could register the fact that
it needs to be called for a certain situation (UDP port, TCP port, etc.),
and the protocol decoding would proceed smoothly.

How is your private protocol detected? Via UDP or TCP port, or is it
at some other layer?
