I have an iMac running SL and a couple Win7 machines. iTunes Match should work well for these systems. The problem I have is my main jukebox is a G4 iBook which is integrated into my home entertainment system.
If use iTunes Match to sync the iMac and Win7 boxes, can I use one of the iTunes sync programs (TuneRanger, Echodio, SuperSync etc) to keep the iBook synced up or will iTunes Match prevent this for any reason?
I am mainly concerned with keeping purchased songs and playlists up to date. Play counts and ratings are not necessary.

Caveats:
All machines except the iBook are used to download songs and make playlists.
The iBook only plays the music.
Not all machines are running iTunes all the time so I can't rely on the sharing feature.
I currently maintain two sets of my music. One on a hard drive connected to my router and one on my iMac.
