	WHO'S THAT TRIP-TRAPPING ACROSS MY BRIDGE?
	(random thought of the day ...  is there a real requirement to 
	do routing at the level of granularity we seem to have fallen into?
	is there any reason to not do more bridging, creating larger broadcast
	domains?  Such constructs are certainly more ammenable to device mobility,
	esp in the absence of workable mobil IP and the derth of EID/LOC splits...
	and there would be less route churn....  lots of good reasons)

	well that has been there for some time - we need not remove the
