Hi, I've been working on NB/OpenGL to make it work on linux. I already have a sample working on my machine that will upload this week.
As for the alien vs ffi vs NB ffi. NB FFI is very flexible, as it implements 99% on the image side, and only depends on a single primitive from the VM side, which makes it easier to understand, modify and maintain. That doesn't mean it's perfect but it's really really good, and each day there's more work on it, adding functionality, documentation and examples. If you plan to make a wrapper, I'd strongly recommend you to use NB. There are plans to have some kind of compatibility with other FFIs in the future for cases were NB can't be used.
