Ah, yes, truly revolutionary
"But if you're technical enough to do this from Apache or anything else, one, there's no problem with that, and two, you're probably not going to understand Unite anyway."
So... If I'm smart enough to set up an Apache server, then I'm too dumb to "understand Unite anyway"? That sounds remarkably like Apple's marketing department.
"What we're trying to do is take something that currently is very difficult and make it easy. We're tying to give you something that you can describe to your parents or even your grandparents. And I believe we've achieved that."
So did Geocities. And look what happened to them. I'll just point out a couple of reasons this will spectacularly fail:
1) Most ISPs (such as Comcast and Verizon) explicitly state in the Terms and Conditions that you are not allowed to run servers of any kind.
2) Upstream speeds. Most ISPs provide people with relatively little upstream speed (1Mbps for Comcast cable, 128Kbps for Verizon DSL), so anything hosted on your system will be displayed to your visitor very slowly. This will be exacerbated when you have multiple people trying to request data from you simultaneously.
3) VoIP. Go ahead and host your files on your own system, then wonder why your VoIP connection is choppy and poor quality.
4) Always-on requirement. Most people don't leave their computers powered on all the time, so trying to connect to their "website" will be hit-and-miss. Some people may choose to leave their computers powered on all the time to combat this, but will probably change their minds once they realize the additional electric cost (and heat) this will cause.
5) It failed before. People don't care where their files are stored as long as it's easy to make a "home on the web". And there have been many software apps and companies that made it easy for people (Geocities, Netscape, AOL, every ISP I've ever had, etc). The thing is, it's a gimmick. People stick with it for a while, then they lose interest. Then again, considering the global dumbing-down of people in the last 15 years, this point may be nullified.
