Andrew,

My sense of NCIP is that it was designed primarly for communication
between agencies that have negotiated a trust relationship offline and
configured their systems to interoperate.

It's not clear to me that NCIP will work well as a protocol for
transmitting ad hoc queries from an untrusted client to a host in order
to discover information about an item. Is your experience/research into
NCIP showing you something different?
