Too many Airplay devices

No, all the Apple TV's on the network will be listed.

I see why you would want to do this....but maybe you also want to do it for security reason ( not to let anyone stream to the incorrect AppleTV ). If so, AppleTV2s have an option to add a password in order to be able to use Airplay....

what is the maximum number of devices the Ipad will see using Airplay?

BoulderTeacher, have you added the remaining 10 classrooms? I'm wondering if there is any limit to the # of AppleTV display options there can be.

Also wondering if you can broadcast one thing to all of the AppleTV devices at once using AirPlay?

Thanks

I was wondering about this myself, being a teacher.

I think the better option (for privacy), would be to either create an ad hoc network for your classroom.

One thing i do is plug in a airport express station and have all devices connect to this. As soon as I'm done, I unplug it and take it with me. It's easy to set up (e.g. you can add a password): just the AirPort utility app. It's on all macs and may be on all iOS devices too. If you can't find it, just download it free from the App store: http://itunes.apple.com/ca/app/airport-utility/id427276530?mt=8

I like the Ad-Hoc recommendation.

That said, I would also broach the topic with I.T. and tell them you need to have firewalls put in place for certain nodes so not everything is discoverable (certain connections can't reach other certain connections). This is better than any privacy/password setting on the unit, and your computers will only show the unit(s) they should.

You could also do this with VLAN's, but I doubt they want to have every room on a VLAN for a variety of reasons.

If the computer techs at BoulderTeacher's school are as competent and willing to help as they are at my school district...then it will take a while to say the least.

The easier way (while not the best solution), in the short and medium term, may be an ad hoc network.

Also, the suggestion of having firewalls in place implies that the school owns all hardware. In reality, there is a growing number of students who bring their own devices. This is a hot topic in certain Canadian schools as the moment (it relieves the school from buying and maintaining additional hardware). I'm quite surprised Apple's marketing is not more aggressive on selling the idea of AirPlay to classrooms and finding solutions to avoid issues like those. Whatever happened to selling "dreams" as Steve Jobs used to say? The devices are there, but the solutions are not obvious to most users. I can imagine a lot of other teachers have similar problems. Finding a solution that fits all needs is not easy.

Apple, time to speak to your marketing team. They could try to sell both Apple TV and Airport Express to education touting its advantages and ease of use. For now, it seems that the marketing is very generic and not aimed at education.

Do all of your apple TV's work? We find so many of them drop the network or they keep the network but don't show up in the Airplay list. We have about 10 connected now, but not showing up in Airplay. Suggestions?
