Powerline adapter (AV2 certified would be nice) with AirPlay built-in. And one model with also WiFi capabilities. Would be nice, wouldnt it? Right now I am using powerline adapter + airport express, but thats kind of messy. Also, maybe it would be possible to make any printer AirPrint capable with this? An USB port in there, some drivers (ok, a LOT of drivers) and you have made your old printer AirPrint capable.
