Embedded OS X Bundle Xcode Guidance

I'm creating a OS X application that I intend to have a plug-in architecture. The plugins will be loaded dynamically. I wish to have a number of default bundles included in the application package contents but I am at an impasse with Xcode 4.x.

Is it the best approach to create another project in the Xcode workspace and deal with it that way or is creating different targets (schemes?) in the application project a better practice?

Any opinions, guidance, experience is thanked in advance

I would create additional targets in your project for each of the plug-ins. Then, add a copy files build phase in your app the copies the plug-in into your apps's plug-ins folder.
