I haven't played around much with this stuff, yet, but I assume that

Personally, my preferred way to handle this would be to refuse to

It is early days for the OGN file. I guess the first priority is to get OGN
up and running with the Flarm Tracking Server.

Have you subscribed to the Open Glider Network discussion group
(http://wiki.glidernet.org/contact)? Perhaps you could influence the
design.
