I know a guy called Ramon Stoppelenburg who did this back in 2001 using the then similarly new medium of blogging without spending a penny: http://letmestayforaday.com/ http://letmestayforaday.com/ .. he lasted about two years on the road just "staying for a day" at people's homes. He now runs a movie theater in Phnom Penh of all things :-)
