You can't stream multiple things at once, at least not in Canada (emphasis mine): > Q : Can I watch movies instantly on more than one PC or Netflix-ready device? > A : 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; however, you may only watch on one device at a time. I've heard that there's nothing stopping you from starting a second stream, but that it can cut off at any time when the system notices, and that they're enforcing it more now than they used to. YMMV in the USA or UK. While you might find it user hostile, I, personally, don't see anything really wrong with only allowing one stream per account. I doubt you can't understand why it's being done either. You have to assume that most people watch a lot more movies via streaming than they did with DVD-Only, both because you don't have the lag time between sending movies back and getting new ones (you just choose a movie and watch it), and because you can't watch a movie then delay the next one by procrastinating/forgetting to send it back (you finish one movie and the next is instantly available without user action). Because of this, there are likely fewer ghost/inactive accounts silently collecting their monthly charge, and content producers probably demand additional funds using the additional viewings as a negotiating tool. Adding additional accounts per household both adds revenue, which is additional funding for content licenses and original productions, and drops the view/account metric, which couldn't hurt when negotiating with content producers.
