If you install the Netflix stock apk on your tablet, it will work just fine. We have confirmation of it working on the ASUS Transformer, Samsung Galaxy Tab 10.1, and the Motorola XOOM. You can take the apk from your phone or you can download it from here, and install it like any other apk. There is no hacking involved.
Update: The Transformer seems to be an issue. We heard from some Transformer owners that it worked, but most are saying it isn’t. Sorry for the confusion.
