I really liked that idea.  Though I changed the name to QRZ which I'm
thinking is a little more aligned with the question of "who is xxxxxx".  I
also believe the format should match the OBJ and KILL format of simply
responding to what is in the first WORD of the message.

So I have added the following paragraph to the
http://aprs.org/aprs12/msg-obj.txt spec:


QRZ SERVER:  During discussion it was suggested that a QRZ server also be
activated.  This server will respond to the message address of QRZ and will
send back an ITEM-in-MSG to the requesting station representing either the
STATION or OBJECT that matches the first  word of the QRZ message. 

If wildcards are used (? And *), then a multi ITEM response would simply be
a list of all the calls/names matching the request. And the requestor would
have to resend his request for the specific match to get the ITEM-in-MSG
response.  If the requested word is lower case, then it is assumed that any
other match regardless of case is being wildcarded.

Hope that clarifies it.
