Thanks for adding that extra information avatari. Yes I was talking only about domains in the "real sense" - you have a valid point with the modified software so you can in effect create your own domain name although this isn't the best way to start a
website hosting as just to see it you already have to get people to install custom software - which in this day of adware, spyware and viruses is hard to convince someone to do. And the more you try to make them get the software the more cautious and suspicious people get.
Hope that helps
