One Size Really Does Fit All - Sort of - Spray on Condoms

Invented by a guy in Germany. Only thing keeping them from selling appears to be that the latex takes too long to dry. You've got to read it to understand this one: custom condoms in a flash

Seems to me the way to go with this would be to combine the mechanism he's invented with something that allowed you to just make your own custom condoms. I mean, if he's come up with something that molds latex to you on demand but the problem is it takes too long to be satisfyingly useful, that would be the solution. And it would save a ton of money if you could just pay a few hundred or something upfront, then have them on an as-needed basis ad infinitum.
