Nvidia has been speaking about OGL-DX interop since last year GTC 2009 and now has just released WGL_NV_DX_interop spec and drivers supporting it..
Seems an interesting extension which useful cases as:
also could be good for an OpenGL video player using DXVA GPU video decode and mapping d3d texture with video frames to OGL textures all without the host to comunicate..
So are you interested in implementing in future releases?
PS: Don't allow Nvidia to be one step ahead in GPU computing
currently OpenCL seems to use only first info..
