asking x not to listen on an interface

[Mathew Johnston <johnstonm@sympatico.ca>]

I've been lookin in the docs, and I cant find any info on how to do
this... I want to stop X from listening on a particular interface... or
even stop it from listening on any tcp port at all.  I'd prefer that it
just use a unix socket or something - something non public.

Any ideas? Thanks
