Hi Juergen,

Short answer is (c).

The long answer is that NETCONF call-home is not needed for dynamic subscriptions.   It is just needed for configured subscriptions.    So on this thread Balazs has just suggested that we reduce draft-ietf-netconf-netconf-event-notifications just to dynamic (so that we can close on the drafts in WGLC).   After that, we would then do a -bis of draft-ietf-netconf-netconf-event-notifications as soon as client-server module completes to cover configured subscriptions.  In this case, draft-ietf-netconf-netconf-event-notifications -bis draft would support any NAT conditions supportable by NETCONF call home, which I believe will be (c).
