[[DR]] The phrase I am refering to is not from draft-eardley-lmap-terminology-02 but from draft-eardley-lmap-framework-02, section 2. In my reading this sentence does not talk about who initiates the session, but about the way the configuration itself is to reach the MAs: 

>  To avoid problems with NAT and firewalls, it is likely that the MA
   'pulls' the configuration from its Controller, as identified by the
   Initialiser.
