Couldn't you run the server on one of the laptops being used for scouting? You could get by with 6 laptops and a little MySQL, I'm sure!

Also, as of what I've seen is that computers can be extremely reliable. My latest applications are threaded to the point where they crash every once in a while when under load (sending 900 requests at a time). I've never had any database corruption or even binary corruption.
Of course, sending 900 requests at a time to the server will be very unlikely as it is neither internet connected (spammers) and you only have 7 users.

The magic of electronic scouting systems is when you put together a ton of HTML and CSS to make a spectacular interface and add some JS/AJAX to make the entire page work without page loads or latency!
Doing something like this will make it possible to sync realtime data between all of the computers!
