Does the following work to prevent DNS cache contamination

	1) have no public access on shared media from cache to external
	network (to prevent MITM)

	2) have separate cache for glue

	3) cache an answer to a query but activate it only after a
	compatible answer is returned for latter query (to protect
	against ID space attack)

?
