Terrain Texture Creation

What tools are you guys using to create your atlas texture map? I've not found any third party products that do a good job of this so far. They all do well for creating the heightmap though.

I've been reading some of what's going on at SplashDamage with megatexture creation and evidently they have a tool that will generate it according to certain variables.

Does anyone know if GG is going to put out some type of procedural texture generator at least? This is a desperately needed tool imo.

Thanks,
