maybe i don't understand what module-tunnel-sink does, then.  how
is it different than a client simply playing to a remote machine?
i.e., is 
  paplay --network--> module-native-protocol-tcp
any different from:
  paplay --> module-tunnel-sink --network--> module-native-protocol-tcp

i've had my current system in place for almost 10 years, i think.  i
worked with what i had.  i've looked at mpd in the past, but since
it wasn't NAS-aware, it didn't serve my needs.  my current setup is
controllable via the web, and especially via text-browsers like lynx.
but i should look at something more, uh, modern.  :-)

thanks.  i feel like i'm missing some documentation.  where are the pa*
tools fully documented?  man pages would be nice, of course, but i'm
old-fashioned that way.  :-)
