The Erlang term format is straightforward, but if you want to set up another node in another language you need to correctly implement/emulate process linking, binaries, and some other stuff too, it's not just a matter of writing a socket to accept and emit Erlang terms.

It's not impossibly large but it's not something one does on a lark either; if there isn't support in your language already it's hard to justify this over any of the many, many message busses supported by both Erlang and other languages that don't have so many requirements.
