Far too rich for me $$$ I'm afraid.
Some pretty obvious alternatives are:
* Position overhead light source(s) behind player.
* Use of dimmers.
I'm Also investigating 3M microslat privacy screen material to stop glare from DMDs. This has been posted before under (I think) Glare Guard. Not cheap, but way less than special PF glass.
Still, might be viable if our glazier mate comes up with sources in Oz?
