I have been asking the same question of Jon Postel recently.  It seems that
Sun's NeWS system usurped port 2000, which has historically been used by
ttcp (a program to test TCP/UDP thoughput).  Upon discovering this I wanted
to have a published port number so that it wouldn't happen again.
Unfortunately, the number czar only handles low numbered ports.  Something
needs to be done about registering ALL port numbers so that this doesn't
continue to happen.

Personally, I don't see why the existing registration procedures can't be
applied to all port numbers.  Are there any significant problems in doing
this?
