What about the idea of an exception list of single-instance
root-window properties?
We have already implemented the equivalent of a dixPropertyLookup
function called PolyProperty. The following URL is an OpenSolaris source
browser query to find the implementation and uses of that function in Xorg.

OK, I worked on this today. The property polyinstantiation itself is
easy enough, but I've run into a problem with the PropertyNotify events
that occur when a polyinstantiated property is changed or deleted -
everyone can see them! Some major changes to the event delivery model
are probably going to be necessary to make this work.
I can't immediately see how it's done in Trusted Extensions. In
TsolDeleteProperty there is just a regular DeliverEvents call to send
the event.
I think there will have to be a way to pass some private data down with
all events, and then have another hook call further down that gives a
yes/no answer for each client.
