Think of each tee node as a 2x packet doubler, then hook them up
like this:

 --- o -------------------
      \
       o------------------
	\
	 o----------------
	  \
	   o--------------
	    \
	     o------------
	      \
	       o----------
		\
		 o--------

I.e., only use "left", "right", and "left2right".
