I believe there will be much larger communities than there is today. It won't be a majority or even a large minority but significant over what it is today. Hence the buy the property today for 10-20 years out.

Certainly not for everyone in every possible situation but there's a lot of people that would choose today if they didn't have to give up communications, electricity and other modern conveniences.

We won't see a flight like we did to the suburbs but I do think we'll see a renewed interest in rural living with all the modern tools of urban and suburban life. When "things" are virtual and physical things are easily shipped, it becomes real as disillusioned people try and reconnect with something more real - but not too real and rugged. ;)
