Thoughts o a way to sync multiple itunes libraries

I was thinking earlier (always a bad start) about my imaginary purchase of a macbook air and macpro.

iTunes has a great interface and options for syncing ipods and appeTVs.

The macbook air has a smaller hard disk than some ipods.

Wouldn't it be great to have the macbook air show up like an ipod so that the you could easily manage the content on the macbook air from your central library. It would work exactly like an ipod and add and delete the relevant content from itunes.

Now ofcourse it could be used between multiple desktops etc . . .

Any thoughts or criticisms welcome. If someone wants to code it then be my guest because I have absolutely no coding skills.

 

So nobody has any ideas about this ?

Shoot it down, say that it has been done before or say that you don't understand it. But influence my ego in some way please.
