There haven't been any further technical issues with this patchset. There is the ongoing argument about usage of node_type, but I think I've made my opinion on that matter clear. Changes to the core code to make CA versus SWITCH operation not rely on node_type can be done as follow ons to this patch set. As such, I've picked this up for 4.2.
