Digital's Project NESTOR has developed something called shX (no pun on
the HP sharedX intended, I didn't know about that and would love to hear
more about it).

We modified the R3 Xlib to provide the dynamic addition and removal of
displays to a running application. Like the HP thing we use a floor passing
protocol ("passing the chalk...") to have some degree of orderliness with
the application. We can deal quite good with different depth displays and
color/mono differences, but there is a lot more work to be done.

We gave our code to some people in the consortium and outside and we intend
to release it through the ordinary channels on expo (and gatekeeper) some
time after R4. First of all we want to base the code on the R4 library instead
of on R3, second we have to fix numerous bugs, omissions and one or two
memory leaks.

The code currently runs on both VAXes and DECstations running Ultrix and
we successfully build sharable versions of most applications in the core
MIT distribution, InterViews 2.5, some DECwindows sample applications and
bozos such as colorwheel.
