By saying that you'll work for room and board, you're not establishing the best positioning. You're much better off separating your consulting practice from your living arrangements. Establish yourself as a credible and professional developer rather than one who "will work for food".

I've been traveling nearly continuously for the last 3 years, funded by a successful consulting practice. If you have the skills, there are plenty of well-paying offsite consulting gigs to be found. Of course, having "the skills" also means knowing how to market yourself, negotiate, and land and keep clients.

You may want to consider the possibilities of geo-arbitrage, having clients in higher cost-of-living countries, and spending some of your time in lower cost-of-living countries.

Travel Well.
