Check out www.unsanity.com and look at their Application Enhancer SDK. That
will allow you to write a bundle (in a special format) that uses the
Application Enhancer to automatically piggyback onto the application you
specify. That way, you don't have to worry about writing the code to
piggyback the application yourself, since it is already done for you. I
haven't actually written any modules myself yet, but the newest version of
the SDK comes with an example, lots of documentation, and of course, the
all-important project template for Project Builder (a HUGE time saver).
