I would think that Skywarn as well as Races/ARES might find a use for this.

Im catching up in reverse order...

I think that is perfect.  It matches the 30 minute "net cycle time" of APRS
already well established.

Excellent idea.  Only comment I would add is to call these
"server-forwarded" messages instead of "server-generated".  Because there
may be other "server-generated" messages, and these terms need to be more

I can see your advantage here, in that you have eliminated the need for a
separate LOGIN message from the CQ message.  This does seem like a good
idea, but it limits us a little bit in all the possible applications for
this technology.  I'd rather keep your original idea of a separate LOGIN
request (which yes, is ACKED with what ever server info is needed back to
the LOGEE).  But keep that separate from the subsequent <groupname> messages

Yes, and this continues to work perfectly for the LOGIN request as you
orignially designed.

Although GROUP CQ's was the original request, the ideas I have always had
for GROUP MESSAGING was a broader application.  All scout camps or even
weekly troop meetings for scouts could just come up on the air anywhere and
communicate with SCOUTS anywhere..

Thanks for taking this ball and running so far with it!
Great work.
