Keep as much direct or hard light off of the screen as possible and you should be ok. Shade light if you have to; it's worth it. A light grey or silver screen would help to improve the contrast and blacks in ambient light. It also depends on the material that will be watched. Bright colorful cartoons, for example, will be able to get away with much more ambient light than say, Dark City. If you are table mounting look into a Greywolf II screen.
I'd look into a Sharp XR-10x projector instead. It's well known and liked XGA projector and has a higher brightness rating.
