Seems the recruiting problem is a big one -- I wonder if there is a job board specifically for companies that are bootstraping abroad? Maybe there are too few companies doing this to make a job board worthwhile.
Have you needed to expand yet? Do potential employees find you through your blog, or elsewhere? If you're not actively hiring, do you still get a lot of unsolicited resumes from people who are intrigued by the lifestyle?
edit: btw, your personal website gives me a redirect loop (Chromium and FF on linux)
