And if attendance was part of your grade?

Actually, I agree with you and Steven that the premise that all have an 
android phone, with battery charge, turned on, with bluetooth enabled, 
is a bit dubious.  At the Univesity of Delaware, students buy a 
'clicker', about $20, with an ID (I presume) and a few buttons for 
answering pop quizzes.  I can only guess that they use bluetooth, but 
with extremely limited function and probably no writable memory, power 
draw is minimal and hijacking not an issue.
