hey guys.

so my dad is a lecturer,

and to stop people from recording the data with mp3, or recording devices,

i thought i'd be smart to investigate the 'wireless' way?

in that we implement wireless headsets.

so is this idea feasable?

how much would it cost to implement them?

we'll need 60 wireless head sets
and im guessing an FM transmitter?

couldn't someone just get the FM and then record that?

is there a way we can 'encrypt' the signal?

cheers

Walkie talkie with headset would work.
