I mean precisely 0 snark, it's genuine curiosity.
TrackIR works with AH. FacetracknoIR and some of the other free head trackers apparently do too.
Why do they work? Do the free face trackers look like TrackIR to AH?
Is the reason something like OR doesn't work because it's an inertial setup that has completely different output?
I just don't understand why something like the free head trackers work, but OR wouldn't.

No problem, Wiley. Snark factor zero detected.
Aces High has been coded to support the TrackIR. Naturalpoint, the makers of TrackIR, offer an SDK for game/sim developers. Read about it
here. Also, if you look at the list of
games that support TrackIR, you might notice that some don't support rotation around all three axes, or movement along all the axes. That is because different game/sim developers decided to support some subset of the various TrackIR features. Aces High supports them all. WTG, HTC!
I guess the free trackers mimic the TrackIR...? Oculus Rift does not emulate the TrackIR. Also, among other things, the Oculus Rift requires the game/sim developers to "...Implement stereoscopic 3D rendering and optical distortion adjustment that produces the correct left/right eye image on the device...", per the Oculus Rift FAQ.
The FAQ actually does answer many of the questions posed here in this thread:
