It's certainly under consideration. I don't mind paying for quality. Still, it's great for some things but material settings, or more to the point, getting support for them is an issue. You mention trans maps, reflections and so on. I see renders where the reflections are very well done, but those who do them aren't really talking. I can get the effects I want in that regard in Povman, which is what I use now, standing on my head. Great skin shaders and mat settings. Light and focal blur behave great in Vray though.
