Harebrained scheme #7; Wireless home jukebox system. Input would be showered with love!

*edit* Just to apologise if this is in the wrong section; couldn't decide if this would belong in hardware or networking!

Hey all! I'm after some advice; here's the longer shorter version...

I'm moving into a new house share with my gf and another couple; we all like the same music and have a good 20k songs between us. We'll pretty much always have something playing in the house and will regularly be having other people around who also enjoy our music - however the house is fairly large - including a 'den' complete with a bar (pumps n' all!) we're starting to build.

So, we came up with the idea of using a couple of oldschool dell laptops we have lying around, along with my pc which has the majority of the music on it and is permanently turned on, to a create a jukebox system. The hope is the laptops would be converted into terminals dedicated solely to selecting music/adding it to a global playlist and outputting to various speaker sets around the house. As someone adds music to one terminal it would update the others ect.

I like to think I'm pretty tech savvy and I'm fine with hardware conversions for the laptops and most networking but I have no idea where to begin, like when you first start tidying a huge mess. Let alone what software would be suitable (or even if plain old itunes dj would work!).

Any advice/2 cents would be greatly appreciated!

 

Looks interesting! And the whole linux side should work nicely with the old lappys. Cheers!
