I actually bought a dozen of these. If you have a lot of wall-warts, even two power strips are going to be eaten up in very short order, while this solution is quite efficient. Have you looked at the price of cable turtkes recently? These are designer rubber spools you wind excess cord around to reduce clutter, the Container Store sells the large model for $14 apiece...

The same thing for VoIP: people will pay for convenience. Probably not as much as operators would hope, but there could be some room in niches like what GoToMeeting or WebEx do. VNC is free and will do everything GoToMeeting can, but GoToMeeting has a much better user interface.

"two or more people can communicate among themselves without the need for a service provider"

Two or more friends, yes. But making it scale to strangers will require a new digital identity infrastructure.

There's no money in VoIP, but there is in identity.
