OK, so I'm a little behind on reading this list!

I have a related question: Let's say you have a big wide bus and you want
to match the lengths of all the traces. Trying to put wide spacing between
all the serpentine traces would obviously require lots of layers. As an
alternative, what do people think of routing the "doubled-back" sections
all on a different layer, preferably one on the opposite side of the same
plane that the "main" traces are run? I'm assuming here that the entire
bus switches at the same time.

Good? Bad?

Thanks,

Paul
