Yeah, this is true. The issue is transmitting high data rates over wifi. HDMI seems to be an order of magnitude higher than WIFI in throughput. Regardless, it would be cool to start with a low resolution version -- there would still be value there.
The hardware component would need to plug into a mini HDMI port, compress the signal, and stream it over WIFI. Can anyone get more granular as to the specific required components?
