I want to make lesson plans that are not necessarily connected to the date book.

I'd like to be able to in the lesson plan to launch maybe an audio file, or a memo or a photo for the student to look at or even an ebook reader if it is a lesson plan that has some required reading

Is there a program out there that does this? I have thought manager, I can make notes and drawings, but to connect to other palm programs out side of it-

Would html coding for palm work for this type of interconnectivity?
