This doesn't make it impossible, but it makes both IR and visible light a bit more challenging.

A large part of those problems will depend on the chemistry of the lights involved, halogen, mercury arc, and LED sources emit practically no IR, while incandescent, fluorescent, and xenon can.
To help with that this year we're using specific 850nm filters, which should help keep down the extraneous light.

We've got enough headroom from the power driver (and spare LEDs) for up to 3, as well as polarizing film to further "select" just our own light source.
