I highly suggest you also talk about the WHY a great deal. I buy quite a few screencasts and knowing your audience is a hugely important thing. Some of us don't have the programming background to leverage and the why of where you are putting code, why it is better than shoving everything into the view etc is important. 5 minutes would be too short I think for most useful learning exercises. I agree peeepcode does this quite well. An example screencast that I would purchase would be using authlogic and then adding and extending functionality to fit your needs. Adding lost password functions, user levels, etc. That would give a nice complete view of a very commonly used item and useful across any project you are going to create on your own.
