STL isn't so good with dual nozzle setup. Currently you have to have one STL file for each color/material. And there are 5 color (5 filament) printers out there.

Cura PU will probably solve that with the per sub-object settings. Right Daid?
You wont need to. In PU, sub objects are separate elements within an object. i.e. a sections of the objects that are not directly connected one another.
I don't know if PU will perform this test before or after the fix horrible but if its before then it should also support intersecting elements (but not attached) to one another.
I say this but maybe I have not understood properly what Daid wanted to say.

No it won't. As it still needs the information about what is a sub-object. And as dual-material prints "touch" it's not properly possible to separate that on load.
STL is fine right now for single material prints. But it won't keep up with the complexity that we want in the future.

STL is just about perfect for 3D printing IMHO, provided you have a robust parser that can deal with precision problems. The best thing about STL is its simplicity - anyone can understand it.
OBJ is perfect for the 3D simulation application I'm writing at the moment, where I want to have information about colour, transparency etc passed from the user to my model. This aspect might become more important with 3D printing in the future (when printers can choose different materials on the fly). And, OBJ lets different objects retain separate identities too. I find that it needn't be much harder to understand - I'm currently simply ignoring features I don't need!
Neither format makes it impossible to have illegal models!
