Re #10: Damn shiny.  Hot swap CPUs are a good thing (I've
  used them on VME) but I don't know of an OS that could
  gracefully handle CPUs disappearing on the fly.  It would
  be nice if you could mark a CPU as "pending shutdown" or
  something and have processes gradually migrate to other
  boards.  Fit solenoids so that a board can physically
  eject itself once it's shut down. :-)
