There is still the issue of implementing a decision tree in the
factory. You eventually have to pick a constructor to call...
I've always been big on table driven stuff. As you may have
guessed, a similar question came up recently...

Hey!
You might look at the Design Pattern named Factory Method.
What you would have is a "Service Factory" that passes back
the required service object when passed the service name. Very
OO, and powerful technique. I use it exclusively when I
implement the Model View Control architecture.
Search on the above key words for more information. This is NOT new
stuff.
Sans adieu,
