Why do you need to run the front controller more than once during run
time? It has a dispatch loop allowing you to loop over multiple actions
during the same request -- so if you want to build up a widget system,
simply create plugins that push and pop from an action stack (this is in
fact part of the Zend_Layout proposal).
The reason for the front controller being a singleton is in part to
simplify access to it from the various other areas (plugins, action
controller, etc), but also because, with the loop, there should be no
need for multiple instances. Can you better describe *why* you need
multiple instances, as well as why looping does not solve this issue?
