New machines for aiding classroom teaching.  First -- for or against wireless? I'm for, with some groundrules.  Is there a switch you can pull on a classroom wall when you don't want wireless?  If there isn't, we should invent one.

Second -- how about a randomizer for calling on people?  That the professor could use to take notes about what happened?

Third -- how about a randomizer that the class could use for calling on other people in the class?

Fourth -- how about a group visualization tool that would show how a randomly generated group dealt with an issue? so the classroom could be in constant town meeting mode? yes, you could vote on how entertaining the professor was.

Just some thoughts.  Tomorrow:  ICANN's stld RFP.
