I hadn't seen anyone point out an obvious point, so I thought that I'd
add it to the discussion.

Not only can the MTUs in both directions differ (because of asymetric
paths), but the MTUs between a pair of hosts can potentially depend
on TOS, precedence, and/or policy if any of these ever gets implemented.

We should probably consider this in any MTU discovery mechanism.
