I'll have to look into that more
If I read correctly, I should be able to open a port on the Mandriva server and have iTunes tap it like any osX shared library. My wife should be able to listen to it all on her macbook or load up her iPod through the normal process. The only difference should be that the files are physically hosted on the central machine with the rest of my data.
She's my ultimate test subject with a love of technology bordering on distain. Average User Test? - Make it work easily for my wife or she won't touch it.
Now, if it was a house of geeks and everybody was Linux comfy they there would be no challenge; NSF, Amarok, gtkpod and it's done.
XMMS I used to use back when the Windows world was al over Winamp. I keep it on my PDA though I don't find reason to use it soo much these days. I will keep that idea in mind though should I need to stream media; I'd not thought of it for that use.
So far, VLC has been the lifesaver for osX and my media needs. The macbook as an out to TV adapter so we pull any video down to the local machine and run it too the TV through VLC. Streaming from the storage server may be an alternate option though.
