Dual Panel relay is running.

Put this address into the extension options on both machines:
  http://192.168.29.210:8787
  http://100.102.182.124:8787

This relay needs a key. Rooms are not listed without one.

Writing without the extension?  /write
Checking the relay works?        /demo  (open it in two tabs)
No key set: anyone who can reach this port can read every room.
