Questions on Features

I am considering purchasing this plugin and have some questions. Can this plug in do the following:

1. No simultaneous log in from more than one machine

2. Keep track of each member’s activity including videos watched and quiz results

3. Can you organize users into groups? Then have a super-user download reports by group.(videos watched by each member, quiz results for each member).

4.We need group id’s when users register.
