OS X icon on insertion of CD

I am trying to create the following behavior:

• Insert a CD on Mac OS X (Leopard and up) machine.
• Upon reading of CD, display a custom icon for the inserted CD
• Drag in an application from CD to Application folder.
• Run application

Up until here I know it can be done but here is the twist:

In the OSX next session, I would like to insert that same CD and display a DIFFERENT CD icon.

I was thinking of having some kind of agent after installation that would monitor this specific CD or some kind of script.

Any ideas in terms o开发者_开发技巧f solving this problem ? thx
