Hopefully we CAN get a concrete answer as to exactly how far the lens shift will go while still meeting the protocol of the lens memory feature.
I am NOT yet an owner of either the AE3000 or the AE4000. However, I have been reading the AE-3000 for about a year and the two AE4000 threads since the AE4000 announcement. (I do intend on purchasing an AE4000 in the next few months and am currently doing the design work to modify my HT to accommodate it.)
From my reading, it appears that the AE3000 does not have a problem doing the anamorphic zoom from 16:9 to 2.35 if the lens is within the confines of the screen. If you get outside of this area, you are looking for a problem in getting it to work properly. Unfortunately, the designers of the AE3000 are confined by the laws of physics and these laws do limit what is achievable. I also suspect that the AE4000 optical path is virtually identical to the AE3000 so it will have the same limitation as its earlier brethren.
I also recognize that many would like to use the AE4000 outside of the window that the AE3000 users found would work. There may well be combinations of screen size, projector distance and user acceptance (of satisfactory results) that will allow the projector to be placed a FEW inches outside of that general recommendation. But that is pushing the limits of the envelope and what may work in one case may not work in the next one. Do you really want to purchase a $2000 projector and find that it won't work in a situation where the envelope breaks? I am sure that the readers of the owners thread would like to read of your failure!
However, I propose that you consider redesigning your theater to meet the conditions that the AE3000 owners found would work. Look at ways and positions to mount the projector to place in the proper location. Consider moving your screen. Evaluate furniture placement so that you can't walk into the projector. Consider tilting both screen and projector so that your setup is within usage limitation. (Remember that the "area" of the screen that the projector must be inside is perpendicular to the surface of the screen. There were a few AE3000 owners who did tilt their screen to accommodate the requirements.)
I hope that everyone who has the position problem has already evaluated the distance-to-screen limitation that the zooming feature imposes. You can find the formulas for calculating this limitation in the AE4000 manual which is available online.
It is my opinion that using the AE4000 (or any projector setup) for a CIH setup will require that the room be tailored to fit the projector and its limitations. You will probably never be able to buy a system at BB or Walmart as a impulse item, and cart it home, unpack, setup it in any room in your home and have it work properly. That is my opinion......
