	I vote for *NOT* using those ports by default. Bram Cohen has said
that it was a bad idea to begin with, azureus and other clients allocate in
the IANA range now, and some ISPs have begun filtering or severely
throttling ports in the "standard" BT range.

	That said, I think it would be nice to give the application the
chance to decide what port it wants to listen on, and maybe even pass it's
own socket fd to the library and say "here, use this"... but if it doesnt
take that chance, proceed with allocating a random port either by not
specifying one to bind, or by picking one in the IANA range that's
available.
