they are just oblivious as to what they are trying to accomplish is just completely a waste of time.

The math doesn't work, it was a novel idea, but like a great majority of the bad ideas in the bitcoin community, hype won't save you and not everything can be done "because bitcoin" in the real world. That only works in our fake little forum world.
Xenland: It's a complete waste of time to build a company around the idea, but it's not a complete waste of time to build an open source repo that allows any number of hosted services providers to deploy Kiosk support (to existing kiosks, for instance) and to provide multiple exchange integration with a tight, well documented API.
See, this way anyone in the world who wants to go full retard can do so very cheaply. You're right about the problem of hosting php on the kiosk, of course. The software absolutely must be hosted elsewhere and kiosks locked down as is standard practice.
