What? You can't use multiple pressure-sensitive styluses in emacs?
I'm surprised ... I thought emacs did everything.

It was in the CAL and I think it was a cluster of Windows machines...
or Macs ... or a mix. I didn't walk all the way around the cluster.
Oops.  I didn't look very closely at how it was working, but it
appeared to me that it was actually a full copy of Network Painter per
machine and they were "sharing" the image somehow. That is, I think
painting and filters were calculated on the client side. Of course I
have nothing with which to back up that supposition. People just
seemed to have realtime feedback on their own machines.

I have no idea how it handled locking/serialization.  The users didn't
need to know and were enjoying their group paint session.  There was
even a text chat window where they were discussing the image.

In any case I think our question needs to be "how would it work best
for the GIMP?". I think a "network tile source" would make sense.
Another argument for abstracting the tile system from GEGL? *grin*
