wouldn't that be neat

Answer 1

That would be a horrible idea. It would be so easy to guess the passwords. Your computer would be hacked in no time.  

Answer 2

You'd need to implement a GINA (graphical identification and authentication DLL) that just does a pass-through for any account other than guest.  For guest, it would always pass a static password regardless of what was entered, and would then log the entered password in the event log, or a file of your choice.

You'd want to make it real clear what was expected in added UI, to avoid users entering real passwords, and thus exposing them in clear text.

(A sample GINA project comes with Visual Studio.)
