I looked into using Bluetooth speakers for smarthome purposes a while ago. The audio is more than good enough, and it's a lot cheaper than "real" speakers. There's one major drawback, though: most BT speakers automatically turn off when they don't recieve audio for a while! With networked audio, you'd want the speakers to stay on, idling until you want to push audio through them. Having to manually turn them on every time you want to use a speaker pretty much defeats the purpose.
