Yep, that pretty much answers my question. They won't help for my situation because they don't do anything to solve the coplanar rendering problem. Oh well, looks like I get to stick with offsets.

I'm placing a sign into my scene using a Billboard with some drawables. The sign should behave like it's a 2D desktop that I can organize flat drawables on. Right now I'm changing depth values for each drawable to control which one is drawn first. For instance, I set the text one unit closer to the eye than the backboard. This works alright, but there is z-fighting when the sign is far away. Could I achieve the same prioritization using render bins? My intuition says that render bins won't help because all graphics objects are treated equally once pushed down the GL pipeline. However, I'm not positive, and I thought asking might help, or perhaps there is an even better way to handle this :-) Thanks for any advice, Chase
