Just as a an idea and a question,

Could Embree be installed into Luxrender and then we could get it as a plugin?

I have no idea what the proprietary issues are but it's an interesting question.

i would also like to restate what we have covered in another thread which is that Embree appears to be functional on Mac, AMD, and of course Intel systems (info which I learned here that is good to know).

i have issues with Lux (basically just the pain in the neck factor concerning texture conversions), but that doesn't change the fact that Embree in lux would be very cool.

i also don't want to push aside the issue of Embree in C.  My gut tells me that we might have a better chance in Lux though.
