That's easy:  Make a common base class, say BrRichTracking 
_that_does_not_inherit_from_TObject_ (directly or indirectly), and put
the common code into members (data _and_ function) of that class, and
let both the Dig and Rdo classes derive from that class, along with
the derivation from BrModule: 


  class BrRichTracking { 
  private: 
    // Common data members 
    ...
  public: 
    // Common function members 
    ...
    void CommonFunction()
  }; 

  class BrRichDigModule : public BrModule, public BrRichTracking { 
    ...
    void Event(BrEventNode* in, BrEventNode* out) { 
      ... 
      CommonFunction();
      ...
    }
  }

  class BrRichRdoModule : public BrModule, public BrRichTracking { 
    ...
    void Event(BrEventNode* in, BrEventNode* out) { 
      ... 
      CommonFunction();
      ...
    }
  }

Take a look at the BrMult[Si|Tile]RdoModule for an example of this. 

BTW. If template support was better in CINT, this should really be
done using a Policy pattern. 

Yours,
