That's interesting background, but I seem to recall that the plug was hyped as a major new feature to whatever version it was first introduced.  Ray Tracing is in the same Hall of Shame.  You guys may be learning a lot from your introduction and development, which may lead to great things later on, but on the customer side, I'll speak for myself, I'm a bit underwhelmed by the hype, not the developmental effort.  Maybe I wouldn't react this way if you'd just slip those new things in without selling them as must-have new features.  That's all I'm saying.  Don't get me wrong, I love what you all are doing.
