Just saw this on the Chaos forums. Click here for the full announcement.

I've snipped this from the Press Release. Looks like they are making progress on the Revit 8.0 bridge to Vray Standalone.

Chaos Group VRay Renderer Being Plugged In

ASGVIS will team-up with Chaos Group at SIGGRAPH 2005 to provide advanced previews of plug-ins for SketchUp 5, Rhinoceros 3.0, and Revit 8.0 that bridge to the new VRay v1.5 Standalone.

Man, I wish I was going, I would love to see how it works! Maybe they will post some more info here soon.

If anybody here is going be sure to report back.
