I think you'd add <handout:0> to the BEAMER_envargs property of the  
node that is turned into a frame.

The only way to use \only right now would be to just write it in the  
text

   \only<4->{The proof used \textit{reductio ad absurdum}.}

Hmmm, maybe this will not work?

Try

#+BEAMER: \only<4->{The proof used \textit{reductio ad absurdum}.}

P.S. Any ideas to make a better way to use \uncover and \only on  
selected
      material?
