Use in school district

I work for a school district and we are thinking of replacing the audio systems in our classrooms. The audio systems we currently use are primarily used to aid children that have difficulty hearing by playing amplified audio from a microphone or computer (dedicated wireless connection between microphone and base, line in) through 4 wired speakers in the classroom. Due to the use of these in all classrooms, my questions are: how many speakers can we setup per classroom? Since this must connect through wireless networks, do the systems support 80211.X? How can we prevent staff from connecting to other teachers speakers and prevent students from connecting to them at all?

Unfortunately, the line-in connection is not ideal for live performances from a microphone, Because it needs to be sent over the WiFi to other speakers, there is a 70 ms delay from input to output in order to buffer the stream. This will cause an echo effect between the spoken voice and the output from the Sonos.

If this is acceptable for your use, the system can have up to 32 units connected. They use the 2.4 GHz band, either 'b' or 'n'. There is no way to easily isolate one set of speakers from another, unless you divide the WiFi into subnets.
