Worth noting that without Displace3D being multithreaded (or a vertex shader), it could easily be the limiting factor in a simple stereoscopic test like this. http://www.anatomicaltravel.com/research/2010/07/displace3d-and-explicit-vectors/ Updated to show the Displace3D in action.

Otherwise, getting the matrix out of the 3Rn is tricky. Not impossible though... Hmmm... Anyway, would be cool to round trip that sort of data. Oh, and the table datatype in metadata is mysterious, as is table output (or matrix) from a tool. The thing with particles is that you can avoid filtering them so that any discontinuous surfaces represented by large derivatives show up as broken, as opposed to streaked. But otherwise... Yeah, who do you think keeps putting the good requests on the VFXPedia wishlist, anyway? :) Yeah, we’re pretty low traffic, so a simple “(shh)” works well. :)

Also, have you tried taking your beauty pass as an image plane and (shh) Displacing it with your position pass (RGB, Absolute, Scale=1)? Works pretty well, much faster than particles, though you do need to bump up the plane subdivision a little if you want to view in stereo.
