Ok, I'll admit it that it's not a business reason to use a software product, but it is ridiculously cool.  Derek Thorslund posted a video about a month ago that demos the features that Project Pictor brings for OpenGL acceleration.  While acceleration of Catia CAD software is really exciting stuff, it leaves a little to be desired for those folks who aren't familiar with how poorly CAD software runs on Terminal Services.  If you're in for a more true to life demonstration, then watch the end of the video when they play Quake 3 in OpenGL acceleration via Project Pictor.  That's some amazing stuff.

Thanks to Doug Brown for the heads up on the video.
