Perhaps something called OLRAS (olras-archives.com)
A file synchronization system to synchronize user-data
with a server (therefore requires a server). The system supports
workgroups as files shared by members are distributed
to all members as they connect. The server is necessary
because otherwise, all members of a workgroup would need
to be connected at the same time to synchronize the workgroup files.

Targeted to very small companies, specially useful
for laptop users whom may or may not be connected to
the network at all times. The server is used to backup private data
and also as a repository of data for users who are not presently
connected: as they connect, their PC gets updated.

      - uses SSH: VPN not required
      - incorporates a private Web space for company-wide documents
      - incorporates WebDAV, for sharing files when file sharing by
            synchronization will not do.
      - Supports archiving of files, previous versions of files may
            be retrieved by the user without IT personnel involvement.
