This is so great! I'm planning a world programming trip, and this is so helpful for that. Do many people freelance on the go like this? Considering a programmer could at least earn $30/hr, at 20hrs/wk thats $2400 / month. Clearly enough to spend a month in each country, even with some fun.
As an expat living in Asia, I have known people like this.
It's a good life :)
Do you know of any resources to start this? I am essentially going to do a pilgrimage around the world, starting from SF. Going to Mexico, Panama, South America, Africa, Europe, Asia, with a hop to Australia. It would be great to talk to some people who manage something like this, and how they manage their freelancing.
