As I understand it you want to tie different servers together. The 
"Server Factory" base class  for TCP connections is an abstraction layer 
which makes it possible to spawn different server protocols , see:


There is no UDP Factory base class that can be used to wrap different 
UDP protocol instances.

I achieve this by writing my own application layer which ties everything 
together- see:


Alternatively - I suspect one could also simply inherit from 
service.Application  and code your "application layer" stuff in there.
