      I have direct control over my expectations, and over the object name.

      I'll backup a bit with that first assurance, and restate it to say that
      by using a 'private' event frequency for the APRS packet traffic (i.e.,
      something simplex and NOT 144.39 MHz), I can reasonably expect that the
      only packets received are event related; the APRStt decaying message
      repeat functions delivers most of the rest of that 'assurance'.

      A shared abhorrence. But maybe a necessary compromise.

      The telling is easier than the doing.

      Tell: center the corral on the object position.

      Do: Dynamically build the corral by treating the fixed format team
      number (the object name) as an index into the corral. [I think I'm
      about to repeat myself here.]

      In this case, it is the event planner/executor, namely me and my
      buddies, that will need to assure those assumptions. We've managed to
      send structured DTMF messages with out HTs, maybe we can manage a few
      additional rules.

      I could always encourage them to use APRSISCE/32, couldn't I?

      Especially since I cannot get, for example, aprs.fi to show packets the
      way I want from an APRStt event last week. Maybe someone can tell me
      how to get displayed on any of the internet APRS sites the all of the
      objects timestamped on 10-AUG-2013 from these queries:


      Or maybe don't tell me. I'll be playing with APRSISCE/32 for now.

      I suspect that all the APRS mappers have some means of exposing info
      about overlapped objects. Even UI-View has such an option.

      But, I suppose, what you are really implying is having an single event
      web-page that the remote audience can point their browser to and have
      all the details silently managed for them.

      I'll spend bit of time getting to know APRSISCE/32 quite a bit better.
