I would pay Dropbox a non-trivial amount of money to solve the problem for
you, because I don't know of any other sub-$10K solution that will cross those
two platforms.[1]

If you could put a Linux box at the second site, rather than a Win32 machine,
you could do more though....

http://code.google.com/p/lsyncd/ is a much better implementation of that same
concept.  However, that would only work one way because you can't inotify
over a CIFS/SMBFS mount.


Anyway, Mitch, if you can deploy a Linux system at both ends you could
investigate using glusterfs or xtreemfs to share data between them, and then
CIFS-exporting that to the Win32 systems on the network.

It would still not provide a perfect solution, but it would at least suck less
than the alternatives.

[1]  OTOH, there might be one that I don't know about.  I have not
     exhaustively research the space in the last couple of years.
