That brightness enhancement film you mentioned seemed pretty interesting so I followed it up
Google showed a number of BEF sites and the claim is that use of the film increases LCD forward brightness considerably while restricting side view slightly.
From what I can gather the film is fitted to the back of the LCD but another site said that BEF film or MLA could be fitted to monitors.
Here is the Google link to that site and the conclusion.

... Demanding applications require further management of the light with

Conclusion
The extension of MicroLens backlight tech-nology to laptop- and monitor-sized LCDs is a genuine and significant technical advance based on years of development efforts, as laboratory measurements and independent experts attest. Sam Matsuno, Senior Vice President of DisplaySearch said, "I have had the opportunity to evaluate many types of backlighting technologies over the past 10 years in display-related businesses, and I have never seen anything that compares with the efficiency of MicroLens. The science of this new lighting technology and its exceptional specular light energy holds great promise for advancing the state of the art of CCFL and LED backlighting, with great potential for notebook-PC and even ...monitor applications
I dont have time to follow this completely but will look harder at it soon because it could have applications for the large Video projectors situation.

Hi remp,
actually i too haven't the time to look at BEF further, i only found out, that it is produced by a daughter company of 3M named 'Vikuiti', maybe others.

the whinner said:
It is two fresnels, thats why I asked about how they could use two. He was on ebay too.....One against screen and other for projection is the only way it would work. That or two lower powered fres. like 2x within focal length for 4x overall. One or the other. I believed ya. Point still is that it wouldnt be bright enuff I dont think. Not compared to my lcd projector atleast.
They are page magnifiers. So its not big enuff to try it properly as my 13" tv is too big for it to fit right against screen. But as I said, its still not gonna be enuff for any real projection use as the brightness isnt there in the first place.
