Great idea, Erlang is very good for such tasks. Native communication between nodes, very high availability and fault tolerance (native as well) using "actor model"[1] and good performance. As an example, in one of my previous companies we built a message broker, which was able to keep 35K keep-alive connections on Amazon Medium EC2 instance and there still were reserves in CPU and Memory.

Plus it's easier to learn it than it seems first time when you see it. Most of our Erlang-developers came from other languages, but they learned basics very quick: 1-2 days until the first commit on production.

The only one thing, it's not so easy to debug it in the beginning. But it's a question of practice, I think.
