Well, I am curious about what you might want to do before a file is opened.
Just off the top of my head, I can't think of anything you might want to do
before it is opened that you can't do equally as well after it is open :-)
But in answer to your later questions - have a look at ido, it must do
something similar in "overloading"/hijacking the find-file command, I
haven't bothered looking at how or what it does, but I do use the mode
occasionally. It definitely hijacks find-file and adds its own
functionality.

Best of luck
