Right, but the question is:

1) is it physically possible for a 15.4g device to send both 15.4g
   frames and 15.4-2011 frames?
   Another email suggests that this can never happen because frequencies
   are never the same.  If so, end of problem.

2) if the answer to question 1 is yes, then 15.4g devices need to know
   if they are speaking to 15.4-2011 devices, and
      a) adjust their frame header bits appropriately.
      b) to 6lowpan fraglettation.
