I live in China, but if I wanted...a... <something made in the us> I pay you, you buy it and send it, and the same for me.
We don't make things here, we buy them from China.
I like your translation idea. Maybe an automated service... buyer names their price, seller translates. Service compares translation to Google translate to ensure it's not complete rubbish. I see two options... buyer cannot see full (or any) translation until after payment, or it's assumed that buyer will pay up even if they now already have the translation.
Another thing that comes to mind is using Bitcoin for micro transactions to facilitate distributed internet services. For instance, is there such thing as a distributed web server? If not, there should be. If so, you could pay individuals to host your content in a way that would make it much more difficult to censor. Similar to what kiba mentioned for file hosting. Distributed encrypted wallet backup?
