Greg,

Some these items are not off the shelf items!  Dave Sharpe wanted to check
into a new firm offering some of these units and they noted it would be a
few month delivery and in the kilobuck range for a single stacked device.
The specs on the units were nowhere near the above specs, but impressive
enough for me to take notice. 

 Someday in the distant future, maybe the trickle down "mil surplus effect"
will put one of these puppies in our hands.
