What is implemented in GTK is a earlier version of this protocol.
It won't interoperate right now, but presumably the protocol in GTK
will be updated to conform. Looking at the web page, it is a definite
improvement over what is in GTK now, though I'm still not completely 
satisfied with it. It does a pretty good job at being a nice simple,
lightweight protocol.

Personally, I'd like to use this opportunity to reorganize DND in GTK
so that we can later add Motif DND interoperability without changing
the the API. (And also clean up some of the mess in
gdk_event_translate.) I'll put out a proposal in the next day or two.
