Not only 5000 if/else blocks, but also additional overhead for message 
queuing.  So, MDP seems to definitely increase the server workload at first 
sight, but at the same time one could take advantage of this additional 
infrastructure to offer additional functionality like distributed processing.

As such, I can only envisage MDP to be feasible in large systems that seek to 
not only offer loose coupling for the sake of interoperatability, but also 
want to construct a system that allows the management of messages.


Thanks!
