hard-wear using 1 pc with several vid-cards would probly be cheaper, but then you've got to run video and serial cables to each screen from your loft having 'dumb network terminals on each screen would probly be simpler and more flexible but more expesive (1gig+ duron 128/256mb an a cheap gfx card with tv out for each pc?) whack a smal boot drive in each terminal (2/4 gb) or you could try network booting from your server but i think u cant do that with xp or 98?
