Ray,

We have different prespectives. The next version of the draft will
try to make the case a bit clearer. On one specific point:

>> Thinking out loud, we could potentially define yet another new extension header 
>> that defines a fork in the header chain: next header field = following 
>> (optional) header extensions, plus length to reach the next header as per 
>> RFC6564; final header field (contained as header specific data within the new 
>> header) =  top level protocol of the final header value e.g. TCP= 6, plus offset 
>> to reach the final payload header in either octets or 8-octet units.

Please look at http://tools.ietf.org/id/draft-zhang-6man-offset-option-01.txt,
although it got no traction here.

   Brian
