However, if by privileged port you mean a port number lower than 1024,
note:
User port numbers range between 1024 and 49151. If you wish to
register a system port — those numbered 1023 or less — it must be done
through the standardisation process of the IETF.
In other words, you will need to write an RFC for your protocol and have
it approved by the normal IETF process. (I think this is quite reasonable
given how scarce such ports are.)
