I would go a step further and say it would be *really* cool to have the M/R framework pluggable. One could spin up a JDK 8 Nashorn implementation (maybe even with a little Reactor integration thrown in for good measure ;) that communicated over jinterface and would like to the M/R framework like a normal Erlang process. Or one could use Clojure or other JVM language like Ruby, etc… ZeroMQ support would be cool here as well…using inproc or even over the localhost to something like Reactor [1] running in a JVM. I'm currently playing with Reactor's Nashorn and network support such that I can make a Reactor participate in an Erlang topology with minimal static and Riak's M/R engine has been on my mind as a good way to test it.
