I'm currently working on a server system like that for our scouting. Run web.py on a machine's port 80 (It's simple. It's python. It works on pretty much any system out of the box. And for an application like this, who needs MySQL when you have Sqlite3? Just use python's builtin support for it.
). A bunch of machines connect to it over a web interface, make POST/GET requests to only POST/GET the data they need, and voila: No data corruption since you've neatly wrapped everything. No multiple copies of things (hopefully). No messy excel sheets. It would be cross-platform (since you're just using HTML/CSS/JS), and you could even set the server up remotely and use 4G connection to access it if you prefer that to lugging your system around on laptops which need LAN (since WiFi isn't allowed at competition).
On the topic of networking, could you use a Bluetooth PAN to do this?
