I have run infinitescreen with elite dangerous game extension enabled then use opentracker to emulate trackir and it actually works great.
But 1. I had to run elite dangerous to get vjoy device to work and then opentracker to emulate trackir.
I recon infinitescreen could have a custom profile area where you can configure for games that have not been implemented yet.
Obviously trackir/freetrack can only be provided unencrypted but I guess users could use http://naturalpointofview.blogspot.co.uk/p/trackirfixer.html as their own discretion if they require it.
