if i understand you correctly, that's not what NAS does.

nas sends audio from NAS-aware clients (e.g.  auplay, others) to
a remote NAS server (nasd).  it won't send arbitrary sound generated
by arbitrary programs.

there's one exception -- there's a shared library shim, called audiooss,
which can be used to "wrap" a program.  it intercepts any usage of
/dev/dsp or /dev/mixer, and ships the request or data across the network
to a nasd server.  i've used this with netscape (long ago).

you shouldn't be running nasd on the machine that's generating the
audio.

again, i'm a little confused, but i think it's terminology.
