Perhaps the least talked about hidden danger with this service is the fact that by establishing a US nexus, you're putting yourself in the crosshairs of patent trolls. Software patents pretty much aren't a thing in the rest of the world, and you can happily trade from abroad with US customers without patent trolls trying to shake you down. That and the vague potential for national security letters should you have possibly interesting information. It's all a balance of risk though and for a lot of people the benefits will outweigh these risks. For a lot of people these risks will never materialize.
