I'm going to have to render out some much larger textures for use with this., seeing tiling would drive me nuts, but in theory as long as it works correctly, ie: wraps to the WB element without the texture affecting or applying over any strokes, dropshadow or glow, I'll be happy. 
btw Brad, not sure why but you images open up in a new FF tab for me, but not enlarged, yet when i close that tab and look at original, its there.. enlarged correctly. Not sure if you knew or why it would be doing that.
