I have a MBP on which I run Logitech Media Server to play on my Internet Radio. This all works fine at home. I'm going on holiday and would like to play music with the radio connecting to my MBP direct (over WiFi). Can I do that? I'm not sure exactly the terminology but at home everything goes through the ISP provided router so it is all 192.168.0.xxx. Is it possible to make my MBP broadcast some IP address so my radio can pick it up as where I'm going will not have internet access - I'll only have my MBP and my radio?
