Yes, and as I said in a previous message, that may be worthwhile since we 
haven't got a lot of real world cases where there is a need for 
inter-policy communication between these two.

But it comes at a cost; the design of the framework is slightly more 
complicated, and user written policies which have some special need to 
communicate with each other can't do so.
