New features: and a few questions concerning setup

I went to a zoominar(from Zoom), about the webinar + and setup of events, etc.

I did have several questions about setup:

1. We need to be able to setup an event that is 4 weeks, daily, with different sessions throughout the day, different times, instructors.
2. Registration.  We need to be able to acquire who attends each event to ensure they are coming to all their sessions or at least a good number of them, otherwise, they don't get their badge of completion!
3. Would registering once for all events be, besides a good user experience, advisable, would we get the registration numbers we require or what would be the cons of doing it this way?
4. Do we need the Multi-event ability in our company account to schedule or setup our event this way?
5. I do like the ability to have a page/portal for the attendees to go to, register(either once or for each event)-would this work in our case?
6. Can we set a time limit on the videos recorded for the event?  In other words, they're internal to the attendees, so no one else should have access to the portal as well as the videos.

I think that's it for now.
