Before I was using Mesh to move files around my home network automatically I was using Live Folder Share. It does pretty much the same thing, it keeps a folder (or up to 20 of them) in sync around your network and online. It’s not as configurable as Mesh and it's not the plat form that Mesh is becoming.
The new Live Sync will bring with it:
I guess there are some people out there using it right now, if you are you need to do some fiddling with your library as mentioned in this post to keep it work.
I used to use Foldershare but since moving to Mesh I don't use it anymore
