re: Working abroad: Anybody done it, and where are the best spots?

I've worked in Europe for 4 years now, but with a company, not as a freelancer. Language is the biggest factor. I speak enough now to get along, but it is still frustrating. My kids are now fluent, which is helpful . We travel a ton and have found the whole experience to be well worth it.
I'll be here for at least another year, but may try a new country for a shorter period before heading back while my kids are still young enough.
