SRV records are not equivalent to either assigned or mutually-negotiated ports; they would require extra messages, extra round-trip times, and/or extra services (DNS) beyond what is currently required. There are other ways to reduce the limits of the current port space, as well as to reduce the dual-registration of service names (which are unique) and port numbers. See: draft-touch-tcp-portnames-00.txt (FYI there is a pending update that includes more detail on the difference between this and Tim Shepard's dynamic port reassignment proposal from 2004) Further discussion on this has already ensued on the TCPM WG mailing list, whose archives may be a useful resource as well.
