I’m spending part of this unusually busy tech-news week at the DEMO conference in Silicon Valley. One of the most potentially cool products I’ve seen is Veebeam, a new setup for wirelessly broadcasting Internet video from a computer to a TV set. In a way, it’s a competitor to Internet TV boxes such as Apple TV and Roku. But instead of getting you whatever movies or shows are available on the box you choose, it gets you anything you can watch on your laptop or desktop, including Hulu, iTunes downloads, and more.
