 1) clients that use the infra
 2) clients can create punt reasons
 3) clients can register to recieve packets that are punted
    for a given reason to be sent to the desired node.
 4) nodes which punt packets fill in the {reason,protocol} of the
    buffere (in the meta-data) and send to the new node "punt-dispatch"
