Home Sharing, but without syncing purchases? At home we have two iTunes accounts. We do not wish to share our purchases as, for example, we have very different tastes in music.

We are looking to purchase an AppleTV that we can both use to stream our content from iTunes.

I've already read on another question that the standard way to handle this situation is to set up home sharing using one of our Apple IDs for all of the devices.

However, I've also read that setting up Home Sharing will cause any purchases on the other account to be added into the library of the home sharing account, and thus copied onto all linked devices. Is there a way to prevent this?
Home Sharing is done under a different Apple ID than the one the computer is authorized for. I have my computer registered under my ID (with automatic downloads on!), and Home Sharing set up under a family ID.

To do this correctly:


Make sure you are signed in to your ID under the Store menu.
Log in to the shared ID with the appropriate command under the Advanced menu.
Voilà!


Alternatively, you don't even need to use Home Sharing. You can play tracks without enabling it, as long as sharing is enabled under iTunes > Preferences > Sharing > Share my library on my local network. Enabling Home Sharing will let you copy files to the local library, whereas this option will not.
