Is that entirely true?  My understanding was that terms sent between
nodes exploited an atom cache, so that sending the same term twice may
be considerably cheaper than sending the same bytes twice.  That's certainly
what the Erlang 4.7 specification description of Erlang term encoding
seemed to imply.
