The peculiar thing about programmers is that they're the one profession that can easily work remotely and travel, and yet they're the one profession that doesn't.
Just don't try to build a business as an indie iOS dev if you want to travel. I've been trying to do this for the last year but this week Apple disabled my iTunes account, insisting that I'm not allowed to access it from Asia since my credit card account is a U.S. account. They've categorically refused to budge on this so now I can't even update apps I've bought through iTunes or the Mac App store. Since the apps I write have to be able to interoperate with other music apps, they've effectively shut me down.
