All the features that you list seem to be included into the AIR Engine, Jay. Have you tried it yet? And if so, what did you think? [size=9px](Don't forget that even though they open sourced it, they still offer technical support for paid customers. I'm also sure that this would include the 2007 PGD Annual winner. But I'd see what Dom finds out about this.)[/size]

The only thing I haven't seen from AIR, and this might just be a lack of artists issue is higher end graphics. Would be interesting to see what LOD and effects you can get out of it.
