Amazon Instant Video

Now that I've completely cut the cord and no longer have cable, I'm streaming all kinds of video.  Lots of it from Amazon, and I love all the deals that they offer.  I'm doing this through a Roku box.  All is well, but the one thing I can't do, and would love, is to have the ability to switch between Amazon accounts.  There's more than one person in my household, so the ability to easily switch between the accounts would be great.

The reason is that we all don't have the same things in our video libraries and being able to switch between the accounts would allow us to view items in the different libraries.  This would make streaming all that much better.
