Perhaps you could share just what you're trying to achieve, for what
application, and how from the application's point of view the master is
different from the slave?  I understand that you have this all laid out
in your head, but the information you've given here is very sparse. This
makes it hard to follow, and difficult to give advice. It's a bit like
discussing the view of a beautiful landscape with blindfolds on. :)
