Detailed Description
The blackboard proxy provides an interface to a simple data-store in a similar fashion to a hash-map.
Data is set and retrieved by using a label. Any player message structure can be stored in the blackboard. At this time it is up to the user to pack and unpack the entry data. The xdr functions can be used to do this.
