Chris,

for the list...

and since i believe that you have implemented this solution with CentOS
boxen... when you get a moment or five...

...would you mind detailing the "*simple* step by step basics" of what you
have done... detailing the processors, cards, and pertinent hardware names,
sizes, and speeds involved please?

and of course any special tricks you have done with your CentOS
install(s)... ;->

thanks
