Id suggest asking someone on the WebAssembly github or Mozilla for advice on how to proceed with a spec. For anyone to even look at the spec it needs to some how be submited under a w3c license.
Thanks for reading, bobajeff. I had thought of using ReSpec to write up something a bit more formal and sending it through the appropriate channels. I was hoping to get some initial feedback though, based on this post, to see if that effort is worth pursuing.
