Same Mnesia database from different Unix processes (was also: Bonjour + Mnesia)

[Jérôme Desquilbet]

Thanks a lot Ulf. I didn't manage to make it work on the command line, 
but in the shell, yes, like this:

$ erl -sname newnode
 > .mnesia:start().
 > .mnesia:change_config(extra_db_nodes, ['othernode']).
 > .tv:start().
 > .mnesia:stop().
 > .init:stop().
$

And yes, it is explained in the reference manual ;-)
   Jérôme.
