I stumbled over this over at cooltools. It sounds like an interesting concept: Be a caretaker and live for free, monetarily speaking, in exotic locations, moving to a new place occasionally. It would fit in very well for (early) retires, particularly those, who could default to an RV or an understanding family, or workers who have done the wise thing and arranged their income and jobs so they can telecommute 100%. Hmm, sounds like me ;-)
