My understanding is that Penn State has theirs in the last stages and should be available to the state in 2007. The trees are being grown on the state nursery outside of State College. I don't think there will be anything available to the general public for quite awhile.
I don't think this is all smoke and mirrors. But, the problem with this type of research is that by the time you get to your goals, technology will have passed you by with something even easier. Think along the lines of genetic engineering, which wasn't even in the pipelines 30 years ago.
