School systems may have more ideas. Maybe print over the network to a
central location and snail mail the hard copy back. That's not very
economical but my point is we should let the users come up with some
suggestions. Maybe the right answer is a $100
net might be faster than snail mail. Or maybe it's just a long walk.
