Karen,

Thanks for the clarifications.

I'm concerned about the software, but it looks like we'll install Hadoop 
On Demand, as someone has already promised a user we'd do it...  If 
there were serious pitfalls, I might be able to slow it down some, but 
simply inefficient isn't sufficient... we have users writing MPI code 
who daily redefine "inefficient"!

Again, thanks!
