I consider the idea a good one, however I'd like to see some things
which should be adjusted/added to the patch and commited in one step
with it:
1. I'd like to see some comments from Paul Anderson/HP and Sun
(Stuart/Alan etc.) whether they like the patch
2. with the protocol extension a client-side demo should be implemented
(for example via using a "empty" input shape for the Xaw tooltips (e.g.
all clicks are passed throught))
3. Xnest needs to be updated
4. Xdmx needs to be updated
5. the patch is little bit underdocumented - I'd like to see both
comments in the header files that this was added later and how a
cliet-side can detect this
6. the manual pages needs to be updated

Please attach the current patch to a bugzilla bug and I can try working
on [2], [3] and [5] this weekend... [6] requires someone who still knows
about the old troff man page format (alanc ?),  [4] should be done by
Kevin...
