I've never had to do something like this... We only pay for one at a time but all three of the PS3s, two ipods, and the PC can run on my netflix... Not that playing that many at once is needed but I decided to test it once and it had no problem connecting. I have noticed that our payment usually glitches at the end of the month and we have to confirm our payment method on the site. Maybe that has something to do with it? Or maybe I'm full of shit and just get lucky.
