Dear PRS Tap-lers,

As it is now very fashionable specially among younger folks to talk and
beam messages with a cellular phone, would it not be possible to send
regular cellular phone messages through SMS and collect them with a
computer up front. Is this kind of class participation really an
improvement or is it just fun to beam around messages in the same way
everybody is talking to their phones?

How are you guys actually measuring the effectiveness of such an
investement versus its cost. Wouldn't the money be better spend on some
nice high tech equipment to perform exiting experiments?
