Just curious as to what people are using for metrics in their IGP and what their reasons are; bandwidth? geographical distance? latency? etc...

In the @Home backbone, we used actual fiber miles (plus a small offset per hop to break ties when a particular route had multiple paths with differing numbers of routers). This, of course, just created a "base" configuration which could be tweaked somewhat depending on what needed to happen to make the best use of circuits.
