Can I suggest you announce loudly and publicly when you're ready to roll out in non-US countries (in my case, Australia), remembering that many of us will have already written you off as "US only" in our heads and will skip straight past future mentions of you, expecting to be disappointed.
Grr. Argh.
I don't know what the market outside of the US but since there's basically no one serving us in this space you would think it would be a huge opportunity if anyone figures out how to crack it.
