@OP:
In my (and my squadmates') experience the "Requires a dark room to work properly most of the time" issue is the other way round, as in, TIR needs to be in dark, and FT doesn't.
I personally haven't had TIR, but my squadmates (with many different TIR versions) have reported that sunlight in the room really wreaks havoc on it. An in my personal experience FT isn't bothered by it at all.
My rig:
M$ VX3000 webcam with IR filter removed + 2 layers of floppy disc covering it from visible light.
Hat with 4 (obsolete configuration but still works with the latest FT version) super bright IR leds (TSAL5100) powered from USB port.
Price:
Webcam 20€
Leds, resistors and wiring 4€
No matter the lighting conditions my setup works perfectly smooth with 30fps.
And yes, I really hope that FT will be supported
