There wasn't much in there that made me think it wouldn't be possible, in fact a lot of it would be possible now.
some of it seems unlikely though, I can see no reason for large format high res displays as motorway gantry signs, unless someday they want to spend a fortune on distracting drivers. Also, although a display on a bus shelter as they indicated could probably be done with today's tech putting several thousands of pounds worth of display in a bus shelter is just asking to get it broken.
Additionlly, the little handheld displays which are clear when not in use is possible now but in their example they seem to have left no room for the electronics, or more importantly, a power source.
A lot of the Surface stuff is already being done, check out microsofts surface
