I haven't tried this myself yet, but apparantly you can use your web cam with this software to do a mouse/headtracking sort of thing.  Perhaps a poor man's version of TrackIR?  If it works well, maybe Scawen could pop it in to LFS as an option if there isn't already a mouse-look type of thing there somewhere.

 Track-IR, I never got this. Hold on, you turn your head left/right to see in that direction within game whilst your eye's are fixed forward. What?
