Actually, I've seen a PCI-based box doing 15MByte/sec sustained read/write
to disk, so it is possible to do it, but it's not likely to be standard
for quite a while. I certainly think that an OC-12 card would be overkill
though. I'm also wondering why someone who can afford an OC-x would be
trying to save a couple bucks by using a PCI-based router.
Once you get into this type of bandwidth, I think a bus becomes a serious
chokepoint.
