That'd be perfect; thanks! I'll have to play around with that once wasm is in a testable state.
As far as compiling within the browser, it sounds like compiling the wasm will be the same process as compiling to asm.js – except the final bytecode format won't be directly executable as JS. If that's the case, then I'd imagine any asm.js compiler could have wasm support added the same way emscripten will.
I think in both of our use cases it all just depends on how easy it will be to execute the code from there. (In your case, the worst case scenario is that you have to post the generated code to a server and redownload it – ridiculously ugly, but not a blocker.)

In the Java applet days you'd actually have to do that -- round-trip your generated bytecode back through the server -- and I was like "Hello, you must be kidding". That's why I don't just assume they've made direct loading possible.
(That link pointed to another link on module loading, a long page I didn't find an answer on right away. Admittedly I'm only curious for now.)
Added: https://github.com/lukehoban/es6features#module-loaders shows module loading of runtime-generated JS code, so the answer is probably yes, hurray.
