This would be really nice to have. Many times I've had some kind of sky dome in my scene, or even a simple backdrop, where I've wanted to use an HDRI image for reflections, but the dome or backdrop obscured the HDR image. There is a "visible to reflections/refractions" option in the object properties dialog, but this doesn't have any effect with vray. So a "vray version" of this option would be nice, especially if you could choose reflections OR refraction independently.
