[Scottish] Network sound systems

[Kyle Gordon]

I'm asking you lot cos... well, google didn't turn up anything useful :-)

Is anyone aware of a network audio system that is mostly seamless? I 
could bring my laptop into the same room as my media box, and 
artsd/esd/alsa/etc would automatically detect the presence of the sound 
system hooked up to it, and offer me a chance to use it instead of the 
onboard sound.

Using upnp AV, rendezvous, bluetooth, anything? Maybe instead it could 
have something in the system notification area that knows what sound 
systems are on the same network, and offer the ability to pick services? 
I know Apples Airtunes device does similar, but up until recently it was 
Apple only. Jon Lech Johansen has cracked the Airtunes key, but it's 
still a kludge to get audio over to it.

Anyone got any ideas, suggestions, hints, etc?

Cheers,

Kyle
