How to maintain 1 iTunes library on multiple computers

Hi,

I have a desktop and a laptop, both of which I want to have the same iTunes library on. I dont want them both to be turned on at the same time so using "sharing" is not really an option.

I currently have my entire library on Skydrive so both computers can access the music with ease. Is there a way I can have iTunes have the same playlists, song ratings/play counts on both computers?

Note: I've tried playing around with symbolic links but im not really sure what to link and where to put the shortcuts.
