XEmacs doesn't support Unix sockets (and neither server sockets).

In theory yes, but a) we also need to change the Lisp side (for N
different Lisps) b) the speed difference is likely negligible as the
Unix kernel should be able to recognize and optimize local TCP
connections c) doesn't work on Windows d) one more thing that can be
misconfigured.  So, I think it's not worth the trouble.
