I don't know what the heck you're talking about, but I suspect Giles just said it's in the current version of Neon PC.
After Effects is a compositing and digital effects package for PC and Mac. It's heavily used in broadcast and fillum work - think "photoshop with keyframes" and you're not far off most of it's abilities (that's understating the case though, IMHO it's Adobe's single best bit of software).
What Rod's suggesting is being able to use Neon as an effects filter in AE, which would be really cool all the way up the left and all the way down the right. Also, as you'd be flogging it to professional graphics kids, Llamasoft would be entirely within it's rights to charge more for the pluginized (ahaha) version as a pro art tool.
Which would, y'know, rawk.
Where it would fall over, if I read things right, would be the live-performance side of things, of having four people jamming along with their controllers to fly the camera and effects layers in Neon. That said, I guess there's nowt stopping someone from plugging a passel of analogue controllers into their AE rig and doing a bit of preflight, as it were.
Eeeenteresting idea, Rod.
