This looks like something that will really work out for me, as I build an automated system. A year and a half ago, I picked up a pallet of industrial computers from a salvage company. I sold a bunch of them and made my money back, but kept quite a few. Right now, I have one mounted on my three tier system running Beersmith and Multi timer. It is nice since they are waterproof and a touch screen.
Here is a pic of it:

On the network thing, you have a few options. Wireless can be run in 'ad-hoc' mode, where they just communicate with each other. Another option, if they are a bit apart, is powerline ethernet. I use that in my house to link up from my downstairs, up to the office. I have had good luck with them.
Anyone actually used one of these things that can tell us the good, bad, and ugly of them?
