"Your account can have up to six unique authorized devices activated (and associated with it) at any given time, including personal computers and Netflix-ready devices. For example, if you're on the 1-disc plan, you can have up to six devices associated with your account, but you can only watch one of them at a time. If you're on the 2-disc plan, you can have up to six devices activated but can only watch two of them at the same time."

If you have more than 6 netflix-ready devices, you either deactivate one and activate the one you want whenever the one you need to use changes, or you put them on a separate paid account.

I'm not sure how Hulu+ does it.

Actually, Netflix bumped that up to 50 a few weeks ago. Haven't updated the verbiage, yet, apparently.
As for deactivating one.. that's no longer possible. It's an all or nothing deactivation. No clue why they changed that, but that came along with the web site redesign...
