How many devices can run off of 1 Hulu Plus account at the same time? The terms of service says 1, but I just signed up today and was able to stream 1 show on my computer and a different one on my iphone at the same time. Any idea of this actual limit? I'm only interested in keeping the service if I am able to stream 2+ independent shows to 2 different TVs at the same time. Has anyone else done more comprehensive testing?
