esd + esddsp + esd{cat,watch,wav,idunno}

esd is a /dev/dsp proxy.  A multiplexing proxy, specifically.  esddsp is a
script that sets environment variables to capture all /dev/dsp activity and
send it over to esd; you run 'esddsp somecommand'.  There's also a command
that can be run to capture an outgoing stream of the data, but I can't
recall which one it is off the top of my head.
