Ledhed2222-Now I understand where you are coming from.
To answer your question-I have two completely different libraries. One is all AAC on one PC, and the other ALAC on my MAC, which is dedicated to audio for the most part. For our iPod (80gb) we just sync off home PC and the library is AAC, and we use about 60GB of space for the portable library.
You can also have iTunes boot to two diffent libraries, where it will prompt you to choose when you click on it to open. This might prove useful for you.
