That's a VERY impressive system! My compliments!
Not to try to add too much more to your obviously crowded plate, but have you thought about a high precision, fully automated convergence system that would work as part of this package, interfaced to the Marquee's own convergence system but with a pile of improvements? I can envision such a system using an upgraded ACON camera that takes precise colorimetry readings and adjusts the contrast modulation circuitry in addition to the usual convergence settings, and with some of the convergence and positioning done by Blendzilla's own processing.
I think it'd be a considerable project, but a slick, well polished system that does its job fast and well would be a super option to add in.
