Serious questions (at any level) are always welcome here...

The following article might be helpful (especially the discussion on 
initialization and reuse of a rule-based KS that is invoked multiple times):

"Embedable Problem-Solving Architectures: A Study of Integrating OPS5 with 
UMass GBB," Daniel D. Corkill. IEEE Transactions on Knowledge and Data 
Engineering 3(1):18-24, March 1991 
(http://dancorkill.home.comcast.net/~dancorkill/pubs/kde91.pdf).

Note that it is also possible to integrate a rule-based system as more of a 
peer engine (not managed by the blackboard-system's control shell, but 
exchanging data and inferences with the blackboard-system side of things).
