Yes, we’ll have to elaborate further on points 2 and 3.
2. Complex rules often include references to more data (and in particular data analysis, stats etc) that of course can be delegated to a DBMS, but at a cost. This is where high performance cache comes in handy, to handle “deeper data”.
3. Wider views on customer / region / time-based policies benefits also from having the data “always available” - this is similar to 2 but “wider data”.
The main point here is that with stateful rules (as in, but not exclusively so, a rule-driven CEP engine), and a built-in OODB mechanism, means that I don’t need to have an SQL writer alongside every rule writer.

The bullets didn’t hit me at all, but hitting on the fundamentals in #1 really highlights why BRMS vendors need to move in your direction, but #2 is too much detail about technical battles that have yet to be waged to clear victory, imo. James and others have good content on #3, but I don’t see why you think it warrants a CEP/BRMS distinction. (Sounds like you want the whole enterprise in RAM and damn the join complexity!-)

James views items 2 and 3 above as “have a CEP engine what do I do with it” issues (ie solutions looking for a problem). Which means we need to blog more about CEP frameworks vs conventional traditional approaches to some of these problems (how CEP marries events, business rules, and persistence with analytics, against the expense of doing all these items separately, CEP and case-based reasoning, CEP versus BPM and case management in favor of customer management, etc).
