I am sharing the iTunes Library from my iMac to my MB Air.
The iMac shows one Shared Library, but the MB Air shows two Shared Libraries. One library has a House icon and has more items, like ringtones and apps. The other library has a Copies icon. When I quit iTunes on the iMac, both Shared Libaries disappear on the MB Air.
I guess on the MB Air that the House icon is the library on the iMac which is used for iPhone synching.
And the Copies icon is the lesser library on the MB Air which is not used for the iPhone.
Or, is it wrong to see two Shared Libraries when sharing?

The house icon denotes Home Sharing, which allows you drag and drop music from one library to another. The other icon represents the traditional (and original) form of Sharing, which only allows you to play tunes from the other library.
