UPnP, properly implemented, requests the port from the gateway device. I
suppose a normal gateway device, being as smart as the typical computer,
would know which ports it has already forwarded to which computers, and only
assign ports as available.
AIM used to be user configurable (I haven't played with it lately), and
Trillian, as well. The user could select any ports desired, and I had, at
one time, a table of ports assigned for two computers. I could configure my
router for two ranges of ports, one for each computer. I see neither of them
offer user configurable ports, either.
Windows Live Messenger relies on UPnP, but I have encountered evidence that
enabling UPnP on the router can be hazardous.
