Live Mesh is a service currently in Beta from Microsoft.  I have been using it for quite a while.  I realized that I keep running into issues with sharing OneNote Notebooks between machines.  Live Mesh is the perfect solution for me. 

OneNote allows you to do this but only on a local file share or a SharePoint Server. 

To work around this I save it just to the default location and then add the directory to live mesh on my first machine.

To do this go to the location normally located at c:\Users\username\Document\OneNote Notebooks\.  If you right click on the “OneNote Notebooks” directory you will see an option to “Add folder to Live Mesh”.

On a second, third, forth, etc machine you can add a mesh folder already on mesh and sync it to your local store of OneNote Notebooks.  From your systray you can access the synced folders.

By clicking on OneNote Notebooks Mesh will allow you to select where you want to store it.

Mesh will ask you if want merge your current files if you have any local on the new machine.

Mesh can be used to synchronize other items as well but for the mobile warrior OneNote is a brilliant tool and I need it on all of my 6 laptops.
