Oh, and FOV can be set through the config files - see http://goo.gl/3ueFz for more info on that.

Hello to you too, friend! You're very welcome, there's no support for Oculus Rift there (yet? I believe it's under review by the devs, the game is still in early alpha) but you should be able to hack together enough with FaceTrackNOIR and IZ3D to see the potential, though there's no barrel warp (or 3d? not sure, still waiting on my own Rift) until/unless IZ3D implement it when they receive their devkit. If you do, be sure to play with the options like mouse deadzone in control (so the gun isn't welded to your eyeballs) and hiding the hud and crosshair in difficulty settings. If you want multiplayer and mission editing features, you'll need to buy the full game, it's well worth it even without Rift support. :)

Also, be sure to keep an eye on flightgear.org - it's a free, open-source flight simulator that will probably implement Rift support soon, they already have configurable stereo 3D and volunteers working on generic tracking support.
