The relevant section is at the very bottom of that page. "Administrators can also use the registry to specify additional folders to probe for add-ins. This feature can be used by administrators to control user access to add-ins. To add administrator folders, manually enter a new AddInFolders key under the Settings key and add a new string value for each add-in folder."
For example, if I create a registry string under HKLM\SOFTWARE\ESRI\Desktop10.1\Settings\AddInFolders called "D:\ArcGIS\AddIns", then any user running ArcMap on that computer will see any add-ins that have been placed in the D:\ArcGIS\AddIns folder as a Shared Add-In in ArcMap's Add-In Manager. The users will NOT be able to delete those add-ins using the Add-In Manager.
Note: If you are running 64-bit Windows, the registry key will be under HKLM\SOFTWARE\Wow6432Node\ESRI\Desktop10.1\Settings\AddInFolders. Also, you may have to create the AddInFolders key yourself under Settings.
If you place the AddIn in a folder that all users can reach (e.g. a sub-folder in the ArcGIS folder) then all users can log in under their own profile and navigate to it. If it is on a network drive then all users could navigate to it from any computer with ArcGIS...
