Comment (by asayers):

 I just want to make sure you're aware of some recent developments in this
 area. Until recently there have been two competing solutions to the same
 problem: nacl and asm.js, developed by Google and Mozilla respectively.
 Recently a new approach
 ([https://github.com/WebAssembly/design/blob/master/README.md web
 assembly]) was [http://brendaneich.com/2015/06/from-asm-js-to-webassembly/
 proposed], and it seems to have buy-in from both parties. You should be
 prepared for the possibility that Google will deprecate nacl in favour of
 web assembly.

 There was a [https://github.com/ghcjs/ghcjs/issues/359 suggestion] that
 the GHCJS project should target web assembly. Luite investigated and had
 some concerns, but concluded that more research was needed.
