I'd agree.. it's a sign of maturity of the cluster concept that they *are*
considered appliances. Of course, if you are a cluster designer/builder,
you'd love to tinker with it, but the vast majority of users shouldn't need to.
here's a paraphrase of classic example in a talk I heard (and I wish I

Speaker asks all the people in the audience: "Those of you with manual
transmissions in your car, raise your hand."
3/4 of the audience raises their hand.
Speaker: "YOU, with your hands waving in the air, are NOT the people who
should be designing the user interfaces. Build them, fine, but I want the
application to be like an automatic transmission.. puts the power to the
wheels in an optimum fashion and I don't have to think about it, manipulate
