Great research, Dennis! Good to know that it is possible to set up
iTunes plus NiceCast on one box. I'm more interested in a live concert
set-up though. Somehow I also like the Sonique plug-ins better than
iTunes visualiser, so I think I'll go with a Windows laptop running
the Audio Visualisation Screen Saver and an extra audio stream cable
to pop into its mic input. I did a test run on that here and it works
fine.

Fired up iTunes v 8.0.1 (12) and told it to open a URL (the IP address of my Nicecast server) and told it to use the "WhiteCap" visualizer.

>> Actually after some thinking (and Halloween, we had 350 kids come to the door last night!), it comes to me that something similar to this is what the WinAmp player originally supported with Shoutcast... You'd run the app on the same machine you used WinAmp to listen to it. The Shoutcast 'server' of sorts ran itself in an encapsulated process, and presented itself as an active stream. Wasn't there a way to take ports like //linein as input as well? I haven't fiddled with it in a while.

>> "IN THEORY" (*grin), you should be able to do exactly as you describe, i.e., run Nicecast on a machine, run iTunes on the same machine and point it to the Nicecast local host/local server at IP 127.0.0. There is a possibility of a performance hit, but then I haven't tried this simply because I actually had the (relative) luxury of having a separate machine to run the software on ... as soon as the project I am running in the background right now is finished I will try this and see how well it works. Well, all of that and the fact that if I have things running on separate machines I can actually test things more easily ... if that makes sense to you!
>>
>> Likewise, your first scenario of using two machines with an ethernet cable should also work (BUT you MUST use a proper ethernet cable, an ethernet crossover cable, to get that to work properly. As you describe it, it would probably be better to a.) have each machine have a unique IP address, rather than trying to point iTunes to the "local host IP" of 127.0.0 since iTunes would look for that on the machine in which it was running, rather than the one running Nicecast and b.) have them on the same subnet ... basically, you could create a "sub-net" with unique IP addresses such as 10.0.0.1, etc., and point to them to each other that way). We have five dedicated IP addresses, two of which are dedicated to my production machine (G5) and my streaming server (G4); the wife and I use the subneted wireless network for our laptops, so that I do have 2 more IP addresses to spare, should I ever need (read=afford the computers!) to use them.
>>
>> To exand on what Per and I are gettng at: There are clearly a number of tools and approaches that can be used to do this. Some of them may work better if you can parse out the "heavy lifting" on separate machines, but the tools are there and we should be sharing our experiences by describing what we use and how its set up to get the effects. The Vimeo site that Todd set up is certainly a good place to share the outputs ...
