Ok, if the "images" are used with a fixed size (as they are in 2D), then it might work ok (although the resolution must be a factor in the positioning), but if you want them to be scaled resolution independently (eg. a quad is always 25 percent of the screen, no matter what resolution) then it might be blurred in lower and higher resolutions.
However, very nice and useful stuff!
