Well said. I have ventured a little into Proscenium, but gave it up, because as far as I could tell, you couldn't share a scene between views. Oh, and the TOTAL lack of interest from Adobe.
Away3D 4 is good so far as my current explorations go, so if you are new to Flash 3D, have a look at that.
Otherwise, just hang around here and enjoy the sound of distant crickets....
