Couldn't this "query/response address resolution protocol" be interpreted as
"server mode" NHRP? As I read the specification, there is not clear statement
as to how NHS interoperate. Could not an NHS be a router? Thus, the NHS are
the "routers" for the NBMA network. Therefore, every NHS has the correct answer
and the NHS forwarding procedures in NHRP can be ignored.

Just a thought!
