Related to this, might I also toss out another posssible feature request?

Suppose you could set a ‘parent’ blackboard on a blackboard, then the GetVariable functions could follow up the parent chain if they did not find the variable within the current level. This would hide the data location from the actual graphs and keep them clean from blackboard variable copy tasks and such and let the graphs treat the blackboard tree as a hierarchy of data. Obviously setting a parent blackboard would be entirely optional. This approach seems like it could be the least impactful.
