tkg, I had forgotten about that significant patent. I remember the NIST Collaboration PR because the names in the Collaboration stuck in my mind as being very significant. I also remember the date those PRs were released, because it was my birthday. 8^) Dunno if we will ever get any details on what Lightwave is working on with the NIST, but they are at the table with some very big names. Lightwave has a lot of irons in the fire and it is just a matter of time before we smell shorts getting cooked...
