  It does until a POS is available. It might still want to even after
the POS is up and running.

  Once sendmail is replaced and it use a POS, that is correct. That's
a while from now. I'm hoping that you're not suggesting that
everything wait until a POS is done. If that's what you are
suggesting, then I believe the LispOS project is dead right now.

  No disagreement here.
