I recognize the desire to be on the bleeding edge.  But the fact is
that any "tip" is an artificial construct -- there is no true linear
ordering of development.  If Sean is off developing CMA stuff, and Hal
is off developing RMPP stuff, their two trees are not really
comparable -- neither one is closer to the "tip".
