You've probably already seen this, but volo can do something similar to what you propose. Might be worth looking at as a reference for work on es6-module-transpiler: https://github.com/volojs/volo/blob/master/commands/amdify/d...

I'm going to do everything in my power to see this happen :)

While I still prefer the Rails asset pipeline approach I am starting to come around to the ideas discussed here.

Great job Ryan. I'm on board with this approach and will do anything I can to contribute
