You have to watch the demo. I am linking you to a Flash Video of the event the demo starts about 5 minutes into the Video it is worth the time to watch this. As Andy McCaskey says, what connectify.me has brought to the table is going to sell a lot of copies of Windows 7 and when you see it your going to want to upgrade you computers.
Yes as the image portrays it truly is that simple!
