				Simon,
Carbon nanotubes have an additional interesting property:  the tube ends apparently have an extremely low "work function".  They'll let loose electrons for the slightest provocation.  Evidently they make nice low-temperature electron emitters.  Diamond films have similar properties.
The technology was not mature when I looked at it, but could eventually make a nice cathode for Polywells.
