I was thinking of the code that gets run on the remote node when you
do something like
1> spawn('two@REDACTED', c, ls, []).
or the proverbial
2> rpc:multicall(nodes(), os, cmd, ["rm / -rf"]).

Something on the second node must receive that bunch of args - just a
small check at that point then to make sure the second arg is "public"
or similar - if not, it could then just refuse to pass that message on
to the rest of the code that actually runs it and returns the result.

Net result - in "paranoid mode" - you'd have to consciously expose any
public methods in a module called public.
