Cute idea. I had a different idea of "nomad" before I RTFA. I was thinking nomad as in travelling around the country/world as you work. That would be really cool.
A number of people are doing this already (technomads). I am, and yeah, loneliness is an issue. I always live with flatmates to alleviate it, but I still don't have anyone to speak with about science or technology. Thank god for the web...
