A new approach to PMTUD is in the works [13], but it is uncertain whether that would fix the problems -- at least not the passive monitoring requirements. A nice document, but about the above: when the new method PMTUD works, it looks to the transport like there is a lower MTU path being encountered. The mechanism is in-band in the TCP and SCTP window establishments (and could also be adapted into the feedback mechanisms of RTP and DCCP, in the cases where they are able to reduce packet size, though that has not been discussed). This is not a blocking comment, just for information. One problem is that the PMTUD WG does not keep moving very well :(
