Yes, perhaps an expansion card with LCD capability could be arranged, no they are not that expensive. Perhaps I will add a communications port for peripherals that can be purchased seperately on these counts (LCD, SD, etc.) without having to include them in the project and make the whole thing more expensive. I will not, however, impose features on people. It will be barebones, then will have the capability to expand with whatever fancy parts you'd like to have.
Then what would distinguish your proposed system from the X6500, Icarus, or Ztex boards already out there? It seems to me you are just re-inventing the wheel with what you propose. That's great if you can manage to do it for less than they are charging, though I suspect that will not be so easy.
