Yeah, there's been some discussion over this, although only some, since Lucid doesn't seem to be too forthcoming with useful details on HOW it works. Right now, it's a little magical chip in between the computer and the screen, emphasis on 'magical'. And frankly, so far, it's detractors have been far more concrete in their reasons than it's supporters.
If you haven't seen this, and care to filter out a few insults,
THIS THREAD is a fairly recent discussion on it, and at the very least, outlines the kind of hurdles that will need to be overcome for this technology to work as claimed.
