Other than price and cleaning, the thing most people seem to forget is that this is technology that they've already expressed interest in keeping for themselves...can't blame them though.

This is just my speculation but...Other companies will figure out how to replicate this process but by then the US patent system will make it impossible for anybody to make it the same way so the prices are likely to keep this at the "special niche" price point for quite a while.

Again, awesome technology...just don't expect it to be affordable anytime soon, let alone purchasable for DIY.
