With the new iCloud, I keep seeing people wondering how they are going to be able to keep sharing purchases among their family members using one Apple ID since the way iCloud works encourages you to have your own.
The problem is, people think to share purchases among their family members they have to use a single Apple ID.That is not true at all.
If you set up Home Sharing in iTunes, you can share purchases among family member computers and devices that are using different Apple IDs. Many people don't understand that although Home Sharing requires you to use a single Apple ID to connect everyone, all of your family members can continue to use their OWN Apple IDs in iTunes and in their iDevices. The Home Sharing account just links up multiple different Apple IDs for you.
Edited to Clarify: Home Sharing among family members with different Apple IDs is NOT limited to just music. You can share purchased apps, books, tv shows, movies, etc. too. Basically anything in your iTunes library. And that includes sharing iOS apps.
It would seem as though it does work with different IDs.
I believe so.. This is an anti-theft service that is put in place in an attempt to detur users from redistributing content. If you have good intentions (like transferring music or apps to your wife) then they figure you can wait 90 days. Sorry.
