IANA registration is pending, or so the latest draft says. Well, what'll 
the draft say if IANA won't hand out port 2000?

I see three possibilities:

1. Advise servers to listen to a standard port, and "MAY also listen to 
2000 for legacy compatibility". Advise servers to try the standard 
port, then 2000?

2. Advise servers to listen to a standard port, site admins to add a SRV 
record, and client to look for the SRV record and fall back to port 
2000 if there is none?

3. Mention only the IANA-assigned port, not 2000, and pretend to ignore 
that all servers listen to port 2000 too, and every client falls back 
to 2000?
