That's pretty cool these guys get to put 1950's math to work in real life. In my experience, I was never able to sell this idea to anyone based on the (potentially justified) excuse that it was completely unmaintainable without a math guy around.

Edit: I can personally attest that potential bootstrappers would find fertile ground making a service to do this stuff for transportation companies. I know of many who basically don't try to solve this problem because they don't have the talent and don't trust their ability to maintain something bought from a consultant. They need a service they can offload it to.
