Well, the new PS3 firmware is about to go out the door with the new feature called RemoteStart, allowing the PSP to turn the console on and off over an internet connection.
This rather weird feature will allow you to access the PS3’s HDD on the go, anywhere in the world over the internet, which would be pretty good if you’re in a nice Wi-Fi hotel or some such place, so you can listen to your games-console based music collection, and watch the movies that are on there as well.
Other features of Firmware v2.00 after the hop, straight from Sony.
