I don't think misusing the LCN/RCN tags is the right way to do this though. A few reasons: - You can't record anything about *why* this is a good route - You can't record different levels of goodness - You can't distinguish between "this is a good route" and "this is actually a signed cycle route" Using an existing tag which has an existing tag, for a novel purpose, purely so that existing routing software will behave a certain way is exactly the definition of "tagging for the router". (Not that I believe in chanting slogans instead of actually spelling out the argument, which is why I've done so above.) And yes, "my use adds little value over a pure shortest route algorithm" - it was never my understanding (or intention) that LCN/RCN tags would be used by routers. But they're used by renderers of various kinds. Steve
