Multiple MY_Controller's

[eluser]jasonjohnson[/eluser]
Is it possible to extend "Controller" in two (or more) different ways? The public side of the system I'm building needs distinctly different default controller functionality than the back-end does.

Currently, I have "MY_Controller" setup to handle the back-end default controller functionality. More or less looking for "My_Controller_Public" -- not sure if that's possible.

Anyone have an elegant solution to this?

Thanks.
