I don't know if what I want is possible/feasible but I thought I'd ask it anyways!
At the moment, I have a laptop (running MacOS X - it's a MacBook Pro) and I connect it to a Hi-fi via a standard line-in/headphones cable. However, I often take my laptop around my room so it's not always near my hi-fi. However, I have a server computer (running Ubuntu Server 10.10) which IS always next to my hi-fi. I was wondering if there's a way to stream the sound from my laptop over wifi, to my server which would output the sound through my hi-fi using the headphones cable?
Hopefully that's written well enough to be intelligible!
