Putting an Erlang-like language on the JVM would really lose all the advantages of Erlang, wouldn't it. The syntax, while very useful, isn't the real strength of the language. It's the BEAM.
I don't think introducing the BEAM is the hard part, I think it's all about the language barrier.
I've been able to introduce the BEAM in a large company (where I work) but the barrier has been they don't know it, they know very well the JVM and they don't care about the language if it can produce a runnable jar.
I would really use the JVM more if I could program it in Elixir.
Using the language for data transformations and such is a breeze but learning the concurrency primitives, message passing, OTP tooling and behaviors is where the real work is in my opinion, when building distributed systems on top of BEAM.
