distributed filesystem over internet/VPN

On this forum was already posted similar question, but it was 4 years ago and didn't give me answers.

I have two groups of engineers that works in far locations connected via VPN. Physically, the connection is a DSL. Currently we have a linux server in one location that provide files over SMB/CIFS. Thus live of people in the second location is a nightmare.

I can change a lot on the server, but one thing must remain. Workstation need to access files using standard windows mechanisms (SMB/CIFS). No extra software (drivers, clients etc).

To solve it, I want to install second server in the second location and use a distributed filessystem that mainly works in replication mode. Files on both servers will be redistributed by samba in the local network.

There is a great list of distributed filesystems on wikipedia.

The most advanced seams to be lustre. But I have some doubts if it will work for me. Lustre is dedicated to a true cluster with a high speed connection (10GigE or special hardware like RDMA). It also stripe space from all nodes, while I rather want to have replication/mirroring.

XtreemFS seams to be more adequate to me. At least from functional site. But it seams that it is JAVA based solution... I'm very afraid for the performance. There is also some limitation for read/write replication.

GlusterFS: according to some blog this filesystem is not good choice for high-latency connection like DSL. (sorry, forum disallow me to publish valid link, add http prefix: joejulian.name/blog/glusterfs-replication-dos-and-donts/)

What is your recommendation?
Had anyone similar problem?

NAME

       filesystem - event signalling that filesystems have been mounted

SYNOPSIS

       filesystem [ENV]...

DESCRIPTION

       The  filesystem	event  is  generated by the mountall(8) daemon after it has mounted all filesystems listed in fstab(5).  mountall(8) emits
       this event as an informational signal, services and tasks started or stopped by this event will do so in parallel with other activity.

EXAMPLE

       A service that wishes to be running once filesystems are mounted might use:

	      start on filesystem
