Did he have any issues with the Propane powered Tippman pump? Combustion technology has been used safely before. The reason it died as an idea for launchers was because back when it was prevalant everybody was using PVC parts and regulation was done in "1 mississippi...2 mississippi..." increments. I am currently building a field using the nail gun that this idea probably hatched from. It's just as safe in the hands of a player as a pressure vessel at 4500 psi is. There's always the potential somebody is going to be an idiot with it, but when used properly it's actually pretty safe.
