I've been hearing about a number of X output extensions, such as PEX,
but am wondering if anyone is working on input extensions.  The NeWS
concept of lightweight, server-resident, event handlers seems to be a
major performance gain for highly interactive clients.

Some simple examples:
    return a string, instead of every typed character
    return region enter/exit, instead of motion events or creating
	(not so free) windows
    various forms of grid snapping

Although NeWS allows each client to define (at run time) its own
server extensions, a small set of hard coded extensions would still
be valuable.  Is anyone doing this sort of thing?  Can it be done
at all with the current extension mechanism?

Thanks for any info.
