Need Advice on Large Flash Project

I have a potential client that wants to present 14 different slideshows (I’m recommending Flash over PowerPoint) on 14 different 37" flat-screen monitors (1 swf per monitor). The slideshows are fairly simple, they just need to cycle repeatedly for about 8 hours a day. Has anyone done anything like this before and do you have an recommendations as far as hardware goes? Should they have 14 different machines, each one serving an individual swf file, or would it work well to have more than one swf running off an individual machine? Thanks in advance for any advice.
