Nothing so far.

However someone else here "found" a very useful document on one of our
Developer CDs. Apologies if this is old-hat and everybody already
knows about this. For others who are interested, it is:

	New Technical Note
	Number:	(they don't have numbers anymore)
	Name:	M.NW.AppleTalk2  (?!? :-)
	Date:	September, 1992
	Size:	51 pages

Quick summary:

	As of AppleTalk V57, the AppleTalk Transition Queue supports
	the ATTTransCableChange event, which will notify "interested
	parties" of changes in cable range, and supposedly "when the
	last router ages out" and when "a router is first seen".
	
	These services are presumably used by the OS and AppleTalk to
	reregister the "Flagship" name and so forth. Any
	NBP-registered Applications have to be updated in order to
	support these events in order to "survive" a zone-name-change.

	Ten pages of "skeleton" code are provided in the doc.

	ATv57.0.1 comes with ARA, Token Ring and other stuff. Quadras
	and PowerBooks came with V56, so they (and previous) models
	presumably can't do this zone0change-support stuff without having
	their AppleTalk drivers upgraded.
