Ahhh excellent.. however I had found that with more nodes things start
to break down with EMP protocol.. simply pinging around on the network a
bit could cause problems.. (not good)

Bill Sparks (js...@sg...) was able to get the SGI version of the 
EtherLite working reasonably well with the EMP. It was the latest 
hardware with the latest firmware, and probably some prevailing tailwind

  involved, but it worked well. I don't know how it would fare under a 
load, but it successfully handled bringing an SGI 1200 up and down for 
many hours without a failure.
