  That is cool actually... My brief perusal of the PA module API seems
  to imply this could work, though it would be a big project.  The
  module API seems to be in a good deal of flux though.

  I don't believe 'merging' nas with PA would make any real sense (I
  don't think the PA guys would think so either)... Supporting NAS
  protocol under PA would however.  What would be the point of the
  auplay client under PA for example, other than a test of PA's NAS
  protocol handling?  Those who want something light and 'simple'
  (without the dependancies PA needs) might still prefer to run plain
  old nasd.

  For PA, the components needed are the network and protocol handling,
  presumably generating samples for PA sink.  I think that is where
  most of the work would lie - encapsulating/condensing the neccessary
  nas components in dia/ (protocol/dispatch/resource mgmt) and os/
  (networking).

  Most of the changes made to NAS recently have involved cleanups and
  voxware fixes.  Niether of these would be required under PA.  Rather
  the protocol and network handling would be the big things needed for
  PA, stuff (especially the protocol) and that hasn't changed in years.
