Rendertime Displacement for Position Displace Op
I use Position Displace Op a lot. It works well for a displacement with a uvw mapped object, but what about when the displacement map is more complicated. 
I also use a great deal of VRay triplaner mapped displacement and the VRay Blend Material that mix different displacement maps. There we have displacement only happening at render time. 
I'm hoping for a way to find that render time displacement and give it the Position Displace Op. 

tyFlow is only able to read data that texmaps feed to it using Max's regular API. It can't access data that a renderer generates internally (like the special VRay maps), unfortunately.
