Actually, we are already part of X.Org.  DMX was checked into X.Org CVS
almost a year ago and was included in X11R6.8 and subsequent releases.
Also, all of our recent bug fixing has been done in X.Org CVS.

It would require some infrastructure work to allow both local and proxy
screens to co-exist.  Integrating the two config systems would require a
fair amount of work.  The dynamic reconfiguration in DMX would need to
be extended to handle the static local screens (e.g., what does it mean
to detach from a local screen?  is it equivalent to a VT switch?).  The
input side would also require quite a bit of work to either make them
co-exist or port one to use the other's code.  The rest of the code
should be mostly separable along screen boundaries.
