Nthusim's opperation looks pretty straight forward and seems essential for such a project http://nthusim.com/wiki/single-head-warping-tutorial but it seems there is a lot to search for appropriate projector lense for such a screen, depending on radius of curvature and available distance in your space from screen, to have projector placed at best position for a good result. There are a lot of good forums around for stuff like that, Ill probably join some and Ill post conclusions here as soon as Ill have them. It seems I just got started, but thanks to all for your input, it really got me started in the right direction!!! P.S. kind forum modderators, please feel free to take this thread to appropriate subforum.
