The only thing is though if on some applications when another user starts it for the first time, it will ask you for the serial#. An example would be Microsoft Office.
Then after you install the application I would download Onyx. When you run your new application the dock icon will appear in the dock. I would click on it and click on keep in dock. When you have all your applications that you use everyday in your dock, run Onyx (its free) and you will see under dock preferences to lock the icons on the dock. That way nobody can move or remove icons from your dock. I have about 40 applications locked in my dock that I use every day.
Quite a few of my applications asked for the serial # after logging into another account. Every user can setup and remove stuff from the dock to there own liking. I like having my dock icons locked in place so incase somebody gets on my systems at home with my account they can't move or destroy anything.
This is just my personal opinion. But try Onyx anyways its free (google it).
