Whatever wireless (or wired) protocol you use, you will need to meet their 
specs. Even bluetooth or WiFi, or anything else. So, there's nothing new here. 
Think of MPEG-TS as the functional equivalent of whatever link layer the other 
wireless interfaces must have. And of course, MPEG transcoders are readily 
available.

I will agree that you can either use an existing wireless standard that the PC 
uses, perhaps bluetooth or perhaps WiFi (assuming you actually have those), and 
then add something to the TV, or you can do vice versa. That is the one valid 
point you made.

As I said, this could fit into a new category of super-low-power white space 
device. The FCC seems very willing to allow white space devices of any kind. 
This would be no more than 0.5 mW, just slightly more than 1 percent of the 
output of the lowest power white space device now, which is specified as 40 mW.

Why not? It's no more difficult than adding a second video card and display to 
the PC.

How do you think a video card transmits a "still image" to the PC display?

Whooee, Craig. This is incredible.
