Starting a process with gen_server:start returns {ok, Pid}, so you can
always stash the Pid away for later use. If you want the Pid for a
registered process you can call erlang:whereis/1 for a locally
registered process and/or global:whereis_name/1 for a globally
registered name. Not sure what you're asking about supervised
processes. This stuff is very well documented - http://erlang.org/doc.

Hope that helps,

Tim
