I’m happy to consider RFC1149  https://www.ietf.org/rfc/rfc1149.txt  for our purposes here, however even carrier pidgeons recommend encryption

Security Considerations

   Security is not generally a problem in normal operation, but special
   measures must be taken (such as data encryption) when avian carriers
   are used in a tactical environment

Always willing to come to a compromise =)

For this morning’s callers. Passenger pigeons are extinct. Carrier pigeon still is a viable option.

 

I originally wrote that carrier pigeons still are on the table. I’m glad that I reread.
