[Beowulf] Pretty High Performance Computing

I guess I don't quite understand why you disagree Prentice.  With the 
exception that middleware doesn't strive to be a classification per se, 
just a solution, it still consists of a "style of computing where you 
sacrifice absolute high performance because of issues relating to any 
combination of convenience, laziness, or lack of knowledge."

This assumes my understanding of middleware is correct in that it is a 
package or entire system that simplifies things by being somewhat 
blackboxed and ready to go.  Anything canned like tuna is bound to 
contain too much salt.
