It's definitely confusing, but I did happen to find a solution for After Effect's camera. In a recent project, we needed a way to compose several images in After Effects and then take all the position/scale properties to papervision and make the scene look the same.
So, to match the PV3D camera to After Effects, you need to use the new FrustrumCamera and set the FOV property to the same as your After Effects camera's Angle of View, BUT set "
Measure Film Size" to
Vertically. Then you just have to make sure the X and Y positions of your layers and camera match, and you've got a place to lay out your papervision scene :) And, just to note, the Y in papervision is the inverse of the after effects Y. Hope that helps!

PS - If you plan to lay out scenes in After Effects on a regular basis, I recommend making a script that exports all a composition's layer properties (position, scale, rotation) to an XML file that you can use for Papervision. Or I can just give you the one I did!
