This looks so cool.

I've been to a fair few boring meetings, and this tech would liven up any of them.

I'm not really sure whether it's only one person/device which can send data to the device, which is then projected, or whether multiple people can do.

If more than one person can send things to the device in a meeting, that'd be absolutely great. Aside from the potential of people messing about, sending stupid YouTube videos to the projector, this would open up great ways to collaborate.

One of the main problems I've come across in meetings is getting everyone's focused attention on the subject being discussed - and this would solve that 9 times out of 10.

Great hunt - very promising.
