Scenario: Right now I have about 8000 computers that need feature updates. I don't want to update them all at one time. It would be nice to tell CM to update one big collection, but do a set number per week. For instance, create a collection of 8000 machines, and set it to update 250 per week until it is done, or set a gradual duration of say 6 months to update the whole collection. This would work great for large application deployments as well. This way, the deployment could also be stopped if problems arise.
