Auto managing multiple iTunes libraries - same songs, different bit rates

[gujaalmac]

I have all my songs in 320kbps AAC format and use a iBook with a IR sensor and hooked to it my hi def and stereo receiver. I have been doing this for 2 years with no problem except my col;lection will now not fit on my iPod (65GB). I know I can get a new 80GB iPod when they release one, but there are benefits of having a lower bit rate on my iPod - multiple times battery life due to less hard disk spinning

So Here is what I want to do:
I want my iBook to hold 320kbps/Apple lossless versions of songs and have mirror library automatically created with 128kbps versions for use on powerBook and ipod.

Anyone know how to automatically(or at least less manually) do this?

It's not automatic but relatively easy to do it manually with:

Doug's iTunes Library Manager

It's how I have Lossless for the home system and 256AAC on the iPod and Shuffle. Switching between the two libraries is easy.

You can have separate playlists and preferences for each library too.

I just downloaded doug scripts... any recommendations on how I do that across two machines.. my iBook server will have lossless and my pBook will have 128 - I would like to buy songs from either machine and copy to other library in different machine (delta sync?) and also would like playlists and track metadata copied (as I tend to fix genre classifications over time on my pBook)
