Next steps: suggestion was to *suggest* that a server might choose to pad its datagrams to the same size as the incoming datagrams prior to getting path validation.  A suggestion only, because the server might know something else about the MTU that suggests otherwise, and this only really provides minimum MTU validation, it's not really PMTUD.
