Env is not fully implemented, tested, or even working half the time anyhow, so I wouldn't count on using it until Bob gets a total implementation completed. The env stuff was more of a test to see if it would work at all in the engine.
As far as specmapping on ATI cards in D3D, don't hold your breath. It might be a little while yet till we can get it going. We were doing some very unorthodox things in doing specmaps, and ATI changed thier driver behavior so that it no longer really works. In short, it shouldn't have worked in the first place, so now we're going to have to use shaders to do it.
