There seems to be a small but growing movement of nomads. The first I met was @ioerror and at least in the way he travels he was quite inspiring. My personal goal with every move for the past three years has been to reduce my amount of "stuff". When I moved back to SF from Seattle everything fit in an SUV. With this coming move, except for those two couches and a stand-up office desk, I could fit everything in that SUV and have 2 or 3 passengers.
It would be awesome if more of the hacker labs around the country were live/work so that visiting hackers could crash there. I know a couple of companies in SF that have "visiting hacker" lofts, like Squid Labs.
