I've just made this freetrack thingy and it looks promising.
It's cheap (if you already own some web cam) - only 4 IR diodes, 4 resistors, piece of wire...
The only problem I have is shivering screen in IL2
Maybe it needs some more testing or tweaking .ini file...
Here are some tracks with diferent "Average" value setting in freetrack.ini file
This project seems to be alive and kicking.
