Nice to meet someone so...decisive...in his beliefs.  Could you  
explain why you feel that the Model component of the MVC web  
framework should not represent the interface to the conceptual Model  
(which is the business logic in your external modules)?

Just to be clear:  I'm familiar with the standard meanings for M, V,  
and C.  I'm trying to have a dialogue about ways and means, pros and  
cons. The intention is to learn and work towards developing a list of  
best practices.  Monosyllabic assertions aren't very helpful toward  
any of those goals.
