About Erlang system nodes

But I found if we run distributed erlang over SSL, it only affects those 
distributed command like spawn_link. It doesn't affect primitive command 
like message passing command - '!' which we concern about. Cause that means 
if we run distributed Mnesia, it doesn't automatically have encrypted 
communication between Mnesia nodes even if SSL is employed. Is that correct?

Thanks a lot,
Renyi.

You can run distributed erlang over SSL. That will encrypt all traffic
between the nodes.
See 
http://www.erlang.org/doc/doc-5.4.13/lib/ssl-3.0.11/doc/html/usersguide_frame.html
for more info on how to do this.
