The DCCP Spec includes content on PMTUD, therefore it's not quite the 
same case as UDP, but the concepts of probing coild be applicable - 
although I do not know of any DCCP implementation that considered PMTUD. 
I'd be happy to thinkl about inputs from people using DCCP - speak up if 
there are key issues that you're experiencing with PMTU discovery and 
DCCP or with DCCP/UDP.
