Russ, This isn't a question of whether routing based techniques are economically viable. It is a question of whether there is any real validity at all in the assertion that routing techniques aimed at reducing power will in fact reduce power at all. First research or other work (such as in industry, aka provider and vendor space) must establish with reasonable credibility that there is something to be gained by a particular strategy. Then if there is a potential for reasonable gains, the advantages and disadvatages can be weighed. With nothing on the advantages side, there is no sense in spending any effort weighing the disadvantages.
