Not sure whether you meant this wrt to the drafts mentioned above, but the PMTUD mechanisms proposed in those drafts operate only at edge nodes close to the end nodes or at the end nodes themselves. 'draft-templin=ipvlx-02.txt' goes a bit further in proposing a new encapsulation that would need to be understood by some (but not all) middleboxes on the path. But, this is a separate issue from the PMTUD mechanism and if you don't want to touch any middleboxes you can always apply the PMTUD mechanism proposed in that document to other tunneling mechanisms that use "standard" encapsulations.
