I have not looked at iTunes4 to find out whether the directories are handled in
different ways when compared to earlier versions of itunes.
We do have .mov streaming files on our servers and we have .mp3/iTune files on a
station that synchronizes a pool of ipods that we loan out to students on
weekends or for trips. The conversion of our existing files was simple - we used
Cleaneer for that. Establishing the directories within iTunes - to make them
look similar to the directories on the server - was a real pain, to say it
mildly.
MP3 files, by the way, do not really stream. It is very easy to download them.
