Speaking from NZ
I would be happy to pay a monthly fee to stream iPlayer content over here in New Zealand. If the paved it in the price range of Netflix and other local streaming products (so NZ$15-NZ$20 pm) it would bring in near the cozy of the annual license.
We have a fair number of British expats over here that would probably be happy to sign up. (I'm a Saffer expat not a Brit)
