> Add functionality to prevent unintended node creation and mechanisms to react on intruder
nodes
>     New HA VH attribute permittedNodeList
>     Nodes register the contents of this attribute as app-state
>     On adding a new node to the griup, the node must check to see its node address is
included in the app-state, if not, refuse to join
>     All nodes periodically (BDBHAVHN has a thread dedicated to the purpose or reuse node
discovery thread?) check to see if nodes exist that do not appear in the app-state. If so
VHN will close env and go into ERROR state.
>     If in management mode don't periodically check the PNL, thus allowing an intruder
to be removed.
