Most flat governmental models have a one member one vote model, which generally requires the member to perform an action each time a vote is needed. This is frequently time intensive and does not take into account members that are not able to be present at the time of a governmental action.
Also interesting is that some tribal models take into account the ostensible wishes of ancestors or other non-physical entities which have no obvious representation in any of these models.
Delegated democracy / liquid democracy ostensibly allows vote delegation. Not sure of any modern or technologically enhanced system that explicitly uses or includes the tribal model.
