This would mean that you can have a passive 3d system with the use of two lcd projectors with great black level performance (far better then dlp).

What are half wave retarders?
You're still missing the difference between what motorman sells and polarized filters. The omega filters and polarization are two different approaches to passive 3D. When you watch a movie in RealD theaters you are using polarization, Dolby 3D uses a similar filter with the same concept of the Omega system. Polarization requires a silverscreen and does not provide the high extinction ratios that Omega offers, but also doesn't require color correction. By using certain LCD/LCOS projectors that have all three colors internally polarized at the same angle you can retain up to 80% of the light output by using a half wave retarder. I won't go into the wave retarder explanation here, if you are interested you can find everything you need to know here.... http://www.projectorreviews.com/projector-technical-blog/passive-3d-projection-part-5.html
By using two Epson 5010, half wave retarders, and a silverscreen made to retain polarization, you would keep ~80% of your light output in 3D and not have to do any color correction. Since the 5010 is a light cannon with great black levels this would be my ideal setup.
Again, I own the Omega kit and have used it with a BenQ W6000 stack. The Omega system COMPLETELY eliminates ghosting, but it also cuts out 50% of the light output and causes color shifts in each projector that IMO cannot be corrected to an acceptable level. I was able to get the colors close but at the expense of another 20-30% light reduction.
This is only my opinion but I would rather sacrifice the extinction ratio (meaning there will be a small amount of ghosting) and gain a bright picture with proper colors by going polarized. If done right it is still hard to spot ghosting with linear polarization.
