Videos hosted for Coursepress Pro? Drip Feeding?

Hi - I'm looking for ways to take payment in exchange for a series of video lessons and think CoursePress may be the way to go. I just have 3 questions:

1) Where do I host the videos? (Amazon S3?)

2) Does CoursePress Pro have it's own video player built-in?

3) I'd like to drip-feed my lessons (i.e. offer a new one every couple of days). Is there a way to lock lessons until a specific time period has passed?

Thanks!
