We have some proof of concept Erlang/Ruby integration in our source base.

Essentially is uses the erlectricity gem to provide a message passing
interface between Erlang and Ruby.

The erlang shim starts a driver which it sends messages to. These messages
are unpacked and the 'applyied' to ruby functions which return values.

The returns are packed into a message and returned.

There is some details on it here:

We used it for a bit and then stopped. Dunno if it is still supported.

YMMV, price of shares can go down as well as up, terms and conditions apply,
etc, etc
