Given how pMTUd works, this speculation should be relatively easy to test (take end point on >1500 byte MTU, run traceroute with appropriate MTU to various points and see where fragmentation required comes back). Of course I'd have tried this myself before posting, except, urm, I can't find a single machine I have root on that I can get more than a hop or two from without running into 1500 byte (or less) MTU.
I happen to have such a machine and an application that specifically tests hop-by-hop MTUs, if there are any specific destinations you'd like checked. It has 9k to the R&E world, and 4470 to Qwest. Bill.
