My particular tv, Sony Bravia KDL-32EX308 has the Xross Media Bar similar to the Playstation 3 Home navigation. I am trying to determine if it uses the same methods of communication that the later 2011 models use. If so, this would make everything much easier. I know from a hardware stand point the KDL-32EX320 is very similar to the KDL-32EX308, and the KDL-32EX320 is included on the list of approved tvs for the Sony Media Remote App.
Side-note:
The firmware is upgradable OTA via Wifi. When I got the TV they had just released an update. I thought, "Wow, that would make flashing custom firmware much easier assuming I didn't brick it."
