Please do.  I read over that page, and am not sure where to start.  I get the 
feeling I would need to start over and create a new .dia, and might be limited 
to what objects I can use?  (like can I use the laptop object?)

"The effect will be some custom properties in your object. They are editable by 
the properties dialog and will be loaded and saved with your diagram. "

Looks very promising.
