oh, i agree. i don't think that i would be able to procure many longer term gigs like that, unless i had some special connections. the scheduling alone would be rough.
i think the ideal solution would be to do something like create my own subscription-based niche web app that would hopefully garner enough users to support the process (which i am in fact working on doing now). and then spend the 'work time' performing maintenance and improving it. and, if extra income is necessary, procure short-term gigs that i could knock out in days/weeks.
If you're working for yourself, then it could work.
Revenue is just one part of the picture. If you can lower your costs dramatically, then you don't need much revenue to support your nomadic lifestyle.
When traveling around Poland, I met a couple of Brits who had moved to Poland for some months to work on their startups. They did freelance work over the internet to pay for their expenses. Thing is, living in Poland you bleed off money a lot slower than you would in London, and you enjoy a much better lifestyle for the same price.
