How do I add a custom field to the login dialog? When the screensaver has been disturbed, or the computer wakes from sleep, my system asks for a password.  I would like to add to this dialog. Along with username and password, there would be a third field asking for user text input on what they would like to do at the computer. After a successful login, the Automator would take the user input and put it in a stickie note in the corner of the desktop.

This is for productivity purposes, as I always get distracted whenever I go to the computer and after a long time surfing the internet, I forget what I actually logged on for. 

I have seen a lot of questions &amp; answers on adding your own text message to the login window, but not any on adding a user input text field.  I have a vague idea of how this might work (which could be totally wrong), but here is what I think:


I need to edit the com.apple.loginwindow.plist and add a custom field that asks for user input? (is this possible?)
Use Automator to paste the user input into a Stickie.
Somehow run a shell script to have the Automator perform this action after every login. (or do I even need this b/c I can do that in the Automator?) 


Also not sure: so I need to use AppleScript? 

Thanks for any help.  I am on Snow Leopard by the way.
Probably not.
I would imagine that the lock screen is locked down fairly tight - imagine a piece of malware that did just that - except the Automator action sent the password to a server in Bangladesh.
