DjMagra’s stuff ‘n’ stuff

So, I want to sync tunes between two copies of iTunes, one on my Mac, and one on my work laptop, done via my iPod. In an ideal world, I’d love to be able to add tunes via either machine, rate them, play them etc, and have all these details synced via my iPod to both machines. Does anyone know how I can do this? I’ve seen iPodRip, but I’m not sure it’s going to do exactly what I want. I also can’t try it right now, as I need to install the .NET framework updates, and so not going to be doing that via ISDN.

Suggestions anyone?
