I don't know the full capabilities either! I know you can do all sorts of stuff with feeds and it IS possible to access Amazon Japan outside Japan (and I'm assuming Amazon China outside of China too?) via shenanigans, but it is too much of a pain and I don't want to give Amazon more money anyway.

Off-topic, but do you know any English translations of the Three Kingdoms (or parts of it)? It seems like there ought to be some but no one I've asked seems able to recommend anything.
