CmisSync vs LinkHubb

Synchronize documents between your computer and your enterprise file server (Alfresco, SharePoint, Documentum, any CMIS-compliant server)

It is like Dropbox for Enterprise Content Management!
For file sharing/synchronization, don't get a new server or rely on the cloud: just use your existing document management server.
Free and open source.
