Re: Trivia: Processor MHz -- MIDRANGE-L

I think the big idea behind grid computing now is using all the "idle time"
of computers in an area, whether they are servers or desktops or *nix or
Windows, etc.  Or that could be just a branch of what Grid computing really
is.  This stuff gets so distorted so easily.
