Two things I forgot to say in my first email:
* If you don't want to use the wsmux you shouldn't have to
  change anything, the old config should work.
* If you are using a serial mose you have to wait a
  little longer to use wsmux.  I plan to port the FreeBSD
  moused deamon, and then serial mice can be muxed too.
