Importing and exporting blender user preference files? I spent some time doing a project in two different computers (personal computer and a shared one in the 3d course), and one of the annoying things was that I always had to reconfigure Blender. It seems that not all settings are bound to the .blend file (things like solid OpenGL lights for the viewport).

Either Blender stores the settings in its installation directory or in the user folder, and both aren't that practical to access in a computer that's not yours (some lock the access to the Program Files folder, for example).

So, is there any plugin that can import and export the user preferences to/from a convenient file (a .xml, maybe?) Installing plugins is something I've been able to do even when I'm not logged in as admin the course machine, so it's a good workaround.
You can use the free Blender Cloud add-on to sync your preferences between different computers. It's a free feature, just requires a Cloud account. More info at https://cloud.blender.org/services
