Well once this has been modified to become an optical camouflage and is mass-production capable (in about 20 years), it will all result in such stealth devices being banned immediately. Only the nations who get them before a respective resolution is passed will be allowed to keep them (that would most likely be the USA, Japan, China and perhaps someone in Europe).
As with all technology though, there is bound to be some countermeasure technology (if nothing helps, infrared or heat detection does - or at least smell-detection, as mentioned earlier), which will in return be countered as well, only to be upgraded to the next level and so on. Still, the militaries of the world would sure be happy to use this stuff... not much practical use for it otherwise

By the way, what does this have to do with 9/11?
