Err sorry, that's wrong. Erlang has its own externalisation format which
is described in some detail in
http://www.erlang.org/doc/apps/erts/erl_ext_dist.html

When we send messages between nodes in the cluster, we just rely on
Erlang to do its magic. If you're using the shovel, then that'll just be
AMQP over TCP.
