Will I be able to stream form AppleTV to other speakers?



if I purchase this will I be able to stream from AppleTV (Black) to other computers like I can with my 1st gen AppleTV?


Also, any indications on when we'll be able to stream from a USB drive attached to Airport express?


Ultimately, I want to run a new 2nd gen AppleTV like my 1st gen one. Ie be able to steam music around the house without needing a computer to be turned on. So the AppleTV becomes the primary music player.
