that's exactly how i use an recommend to anyone - one appleid for things which need purchasing and are shareable across a family ( basically iTunes and the Mac App Store) and one for individual services such as iCloud, facetime and iMessages. something like A single shared family-email@gmail.com which every family member uses for iTunes and MAS on their iDevices and Macs while each person uses their own email@gmail.com as Apple ids for Facetime, iCloud and iMessage.
