After sending this, I realized it's slightly wrong... Until the cost of installing a new MB of memory is obviously more than the cost of a link/path (including the router, of course), the economics will always sway in favor of adding more state to preserve (or control) link usage. Since the cost of adding a new link generally includes the cost of adding more memory in some way, shape, or form (IE, the one cost includes the other), I don't see how this balance is ever going to be changed. Of course, I could be wildly wrong. Someone could look back on this line of thought in ten years and say I just didn't understand some new model or paradigm, but in current terms, I don't see any way around the preference for more state against buying more paths. :-) Russ
