Hi Jeff,
thank you for bringing up for discussion this interesting proposal. A
question and a comment ahead of the meeting to save us time:

   - which applications will benefit from monitoring path MTU (PMTU) rather
   from using PMTU discovery and updating the value;
   - note that "The Don't Fragment bit (Section 2.3 of [RFC0791]) of the IP
   payload, when using IP encapsulations, MUST be set." is only applicable to
   IPv4 environment as IPv6 does not allow IP fragmentation.

Regards,
Greg
