You're right on all those points. The reason, which I didn't explain enough, that I'd suggest you'd look at pony, is that erlang's scheduler and calculation model are great for routers, but less great when you need to do a bunch of matrix transforms within a 120Hz frame budget. Pony compiles through LLVM and has, e.g., native integer types, so is a little closer to the standard OpenGL user sweet spot, where tons of fast math matters and everything is pretty strongly typed. That said, if you get it working on erlang, so much the better, and good luck whichever way you go, sounds awesome!
