The problem, as with any DRM scheme is that the plaintext is available somewhere. Figure out where the buffer is, read it via the JS console (or Pin if the browser won't cooperate) and you're done. Asm.js probably offers as much protection as a normal binary, although the niceties of the JS runtime might make developing patches to dump streams easier than in native code. I'd definitely say it's feasible, although I'm not sure it would add much beyond what Flash/Silverlight already provide.
