Affiliates Plugin- question- uses

I have a site, that will be offering classifieds, directory, and membership. When setting up the affiliates plugin and using on all 3, will the same affiliate program work on all 3?

Let's say an affiliate, named Bob, signs up as an affiliate. Can he promote all 3 from the one sign up?

What if a customer joins a paid membership, and Bob gets paid commission for that. Then the same customer decides to run an ad in the classifieds. Will Bob get paid for that one? Same for paid directory listing?
