    No, the problem is vagueness.  We can't tell from your description
what you want to do.  A real-time desktop application? Warehouse-scale
computing?  Your own "cloud"?

    Incidentally, bear in mind that once you scale beyond tens of
machines, error detection and recovery starts to dominate
the problem.
