We've been using Clearpass since 2013 to manage Airplay with classroom Apple TVs via Airgroup. We've since replaced all Apple TVs with 4th generation ones and all of our end-user devices are capable of peer-to-peer Airplay. I'm wondering if it makes sense to keep using Airgroup, or just rely on the clients to do peer-to-peer and leave the controller/Clearpass out of the equation altogether. What are other schools doing these days?
