What if I publish a proof-of-concept patch that adds a horizon to
LX8000 and others, circumventing this switch?

I think I can assemble one for LX8000/9000 (from LXNav) and the
upcoming LX Zeus (from LX Navigation) in a matter of a few days. It
will not be detectable without special equipment. And it will work
without the new AHRS hardware.

(Pilots interested in such an exploit may send me a private message)

If mainline XCSoar gets banned, I will demonstrate that most other
products must be banned, too. Better keep an old first-generation
electronic vario at hand when you attend a contest, to avoid surprises
;-)

I have already written a patch for LK8000 that pretends to be
"LKCOMPETITION" but doesn't actually disable the horizon:

http://git.xcsoar.org/cgit/max/lk800...5859495c5818d2

Given the existence of this patch, contest organizers cannot be sure
whether a pilot's PNA runs an approved LK8000 version or a fake
full-featured version with my patch.

I'm not trying to support cheaters, I just want to make clear that
banning new technology is not a useful measure to prevent cheating.
