[erlang-questions] Tracing traffic between nodes

This is surprisingly difficult. It seems that if there are two Erlang
nodes, my code would probably work.  If there's a C node involved, it
seems that replacing message sends/receives in the C code with
something that does the proper logging is the best bet, as I don't
think the Erlang runtime environment is up to the task: it simply does
not know where messages come from.

Wireshark has an Erlang distribution parser, which is pretty cool, but
because of cacheing of atoms, it's not something you can just start up
and have work, either, in terms of having a log of what was actually
sent where.
