support for local servers on pf_unix sockets?

 Anybody thinking of support for pf_unix sockets? Or does such a patch
exist already?
 Although the bigger servers/services I use xinetd for can deal with
using tcp/ip and loopback locally, there are some situations, esp on
very constrained & embedded systems, where I'd prefer the local cx to be
pf_local/pf_unix sockets for perf & working-set. xinetd has so much
great logging & mgmnt it would be great to leverage for these rather
than rolling something new.
 Apologies if this q is brain-dead or faq -- didn't find it in faq's,
google or a troll of the mailing-list archive, and a quick browse of the
source didn't look like this was trivial, either, but perhaps I didn't
look well enough.
 Thx for any thoughts, n@
