Well it's not as easy as you think : it's business specific software. I work in public transportation : one company provides us with a way to bill customers, from the time they use their card in a bus (you would have to build the card reader too) to sending a monthly bill. The other company provides us with a way to track our buses (specific hardware too), and there's even a supposed way to optimize their flow. But if someone wants to tackle the challenge they'll need a "bit" more than an afternoon ;-)
