your dream is a good one. believe it or not your best route to a sustainable version of this is a startup. why? - you need to love something in order to be dedicated to it wherever and whenever (its mostly about time zones). - you want something where effort=return and bullshit = zero.

no matter what path you take to achieve this kind of freedom balance will be required. in the case of your own business you will need to spend lots of in person time with your partners and have great discipline with communications. if you don't have pre-existing relationships of several years that's how long will it take to get started. at least it has in my case. the payoff has been huge; its lead to a company where everyone lives and travels entirely as they want. good luck
