[SAM] SAM Overlay Protocol

[Matthias Waehlisch]

Hi John,

  just one short remark to draft-buford-irtf-sam-overlay-protocol-01.txt:

  The GroupId in the tree lifecycle messages identifies "the overlay 
address of the root of the tree". Although the term is almost used in this 
sense, it is not true in general. Two examples: CAN multicast and the 
prefix-based bidirectional shared tree approach, which we presented in 
Chicago.

  Maybe we can rename the description to "the overlay group address".


Cheers
  matthias
