Thanks for the info Pogson, it's very helpful. I've only just started to experiment with Linux for this kind of stuff. I'm afraid that I'm more of a Microsoft Windows person, so when it comes to what things need changing in Linux, I'm a bit at a loss. The machines that I'll be using are laptops, so they will be connecting through the wireless. Is it difficult to get them working in this way? They all have HDDs so I think I'll have them booting up from there, instead of PXE. Don't think you can do PXE boot through Wireless. I was thinking of using something like Ubuntu, seems fairly easy to get that one working.
