edit: For what it's worth, my impression at the time is that this is an industry ripe for disruption. Every city / state / county has to deal with road striping. They do it through a combination of their own rigging and/or various firms who specialize in this stuff - both hardware and software - but where there isn't a dominate provider. It's classic B-school stuff: take a cottage industry and standardize the process, outperform your competitors because of your standardization, and become the monopoly.
