I could see an open source/open hardware system with a

Everybody would broadcast position protected by a

It would be nice to allow the contestant to play with

My informed source says the time delay (10 minutes or so)
would be used
ins=
tead of encryption. The time delay can be built into the
transmitter.
Thu=

10 minute delay ? I thought the idea of FLARM was for safety,
perhaps they are they expecting messages such as:
“there was a glider 2 miles out on a collision course 10 minutes
ago, the fact that you are reading this message suggests that you
saw and avoided it without my help ! Have a nice day”
Sounds rather like something the late Douglas Adams would come
up with.
