Compare and contrast custom meta box frameworks

There are a number of ways to add custom meta boxes to WordPress admin, from coding against core functions, through code API frameworks, to GUI interfaces. All of these have a place, but which is the right one for your project, code style and coding level? In this talk I will provide code examples and illustrations of the code techniques for each of the methods. By the end of the session I would hope that you would be able to make an informed decision as to what will work best for you. Time permitting, I will also show you how to extend the frameworks.
