There needs to be a singular dialogue for all port assignments for all
protocols. It's beyond the scope of
an individual dissector or set of dissectors.

Subject: Re: [ethereal-dev] Binding multiple ports to one dissector
Actually, I think doing it like I did it in packet-diameter.c is the wrong
way to do it. Once several dissectors do this, the preferences dialog is
going to get un-wieldly.
I think a higher up package needs to create the tab, and different dissectors
need to add their ports to it. Maybe packet-tcp and packet-udp?
Just my $.02 worth
