windows 7 - Hide public shortcuts in desktop without administrative privileges

I've looked on the multitude of questions related to Desktop icons in Windows 7 but I haven't found the answer I'm looking for yet.

The goal is to have Desktop icons on the Public folder such that all users see them by default. However, if a user wants to hide all the shortcuts from the Public Desktop, he should be able to.

The last part I haven't found a way. So far it seems to be a "all or nothing" situation. Either you have the shortcuts on a per user basis or having them in the Public/Desktop folder forces everyone to have them visible without being able to change this themselves.

Basically I want the users to be able to disable the integration between their Desktop and the Public one, effectively only seeing what they have in their C:\Users\\Desktop folder.

Edit: Focus on the ability to disable the integration of the User's and Public Desktop.
