Can the projector be 20 ft away from the screen?

I'm considering buying a projector to use in my home theater setup. I live in a loft...my room is 70 ft long by 22 ft wide and my ceilings are 25 ft high. Ceiling mount is almost out of the question and I don't want a projector sitting in the middle of the floor.
18 feet will have to be the minimun throw for me to consider for a projector. I would like the projector to be against one wall and throw the image 18 to 22 ft across to the other wall. Is this attainable and still get good picture quality?

Attainable???...Yes. Practical???...Here are the issues.
You didn't specify which projector you would use. Knowing the projector would indicate the lens ratio. A simple equation is to divide the throw distance by the lens ratio and you will get your screen width. Assuming a 20' throw (LENS to screen) and a lens ratio of 1.5 (just a general assumption), your screen width would be 13.3'. This gives you a screen height of 10', assuming a 3 x 4 aspect ratio. Since we don't know how bright the projector is and how much ambient light is in the room at any given time, there are more factors to explore. I realize I made quite a few assumptions, but if you fill in the missing info I can make some suggestions.

Mitch, like any audio component you can audition at home, have you considered auditioning a projector in your room? You didn't mention if you were interested in LCD, DLP, CRT, ILA, etc., or if you were buying used from a dealer or from Audiogon, but if you can audition a projector in your room you will gain answers to many of your questions. Many LCD and DLP projectors are small enough to make an audition quite simple to do. I applaud you for wanting to do your homework.
