RE: Question on LMP

[Jonathan Lang <jplang@calient.net>]

Martin,
  As you suggest (and as per the discussion in Minneapolis) we have further
decoupled the dependence of the control channel from the data-bearing links
by removing the CCId from the link-specific messages.  The source IP address
identifies the originator of the LMP message.
