In my honest opinion, this would be an amazing choice of stretch goal option. If you offered inside out tracking, then every HMD could do roomscale without the need for buying lighthouse. You could also do Augmented reality with inside out tracking.
If Pimax chooses inside out tracking, you will truly have a next gen HMD that is useful to everyone who owns one, regardless of things like vision problems, (which might make eye tracking problematic for some.)
