I have been a freelance writer for the better part of 10 years, and there is really nothing I would rather do.  From Economist WTO forums in Beijing, changing over to the Euro in Estonia and the first female President of Argentina, I can can't or at least shouldn't complain, however, not knowing where my next paycheck is coming from is both the cause and solution to most of my problems, to quote H. Simpson.  I have recently begun working for www.outscribes.com which pays me in dollars, I can choose between full or part time, and never stop moving, but whilst make a cracking good wage.  They let me write about whatever I want and clients are happy to get a good writer (shameless self promotion) and not pay too much, so the work is just pouring in.  Hope this helps out some of my fellow nomads.
