My only reservation with CQSRVR as a group messaging solution is that it 
is more of a group notification solution given the time limits between 
allowed transmissions from any single source.

When I first learned of the group messaging feature (having missed it in 
my first 10 readings of aprs101.pdf), I was intrigued enough to put it 
on my ToDo list for APRSISCE.  It's going to occur at the same time that 
I beef up my messaging support including the streamlined acks.

I wonder if javAPRSSrvr's callsign prefix gating feature applies to 
message destinations as well as packet sources?
