   To get info about what an AP (access point) can hear, dumping the ARP   
   (address resolution protocol) table or collecting broadcasts seems   
   like likely methods.  There are various ways to limit the scope of the   
   ARP table.  The easiest way is to reduce the number of entries in the   
   table one entry and assign a static ARP entry.  Only one pre-specified   
   device can connect.  Another AP might be able to hear broadcasts from   
   the pocket AP, but I suspect that it will not add ARP table entries   
   for devices which cannot connect.  This needs to be tested (not by   
   me).   
      
   Jitsi meeting beckons.  Later...
