This year we are developing a scouting program based off of Nintendo Ds's, Laptops, a computer to act as a server, php, and MySql.
There is a way to do it for a pretty cheap price (if you already have a DS)
I got the idea off TheOtherGuy (

I have also heard somebody doing a system for the PSP and the iPhone.
Just search PSP, NDS, iPhone, or just about anything else on CD, and you'll find tons of ideas to work with.
