I think the good thing about domains, and to a further extent developing them is the startup cost is so incredibly small. Literally you can put up a few pages every now and again, pay $6 a year to keep the domain, pay $20 a month for hosting an unlimited number of domains, and providing your site makes a couple dollars a month in adsense and the odd affiliate sale your already in front...for really very little work. If your clever enough too use the many labour saving options there are, the story gets even better.
Multiply that dozens of times over the course of a few years and its a lot of money. What excites me is the opportunity it presents for people to work in locations they would normally never have dreamed about in 99.9% of 9-5 jobs.
All i need is a computer and a connection and i can work literally anywhere in the world where they have a decent network, 56k if necessary.
Here in Australia, i think your going to see a lot of freelancers working online moving out to the bush to work, because housing is so much cheaper, the lifestyle generally that much healthier, hopefully resulting in a lot of small country towns being reinvigorated by people actually moving in for a change, rather than moving away.
While i hope to travel in the longterm, what im personally working towards in the medium term is buying some land outright, probably in Tassie. That will bring one step closer to a personal freedom that i couldnt hope to achieve doing most 9-5 jobs working in the city if i didnt want to carry a $300,000 mortgage for the next 30 years.
