Hi all;

I have a client who has multiple (50+) small sites with 2-10 PC's at each
site, most with no network file storage.   So far I have been distributing
small files to each site using FTP from their central webserver, and that
has been working fine for small files.  We're now investigating staging
larger files to these sites (100MB+, thanks Windows Live!) and utilizing a
cloud-based file depot for that purpose (Sharefile in this case).

To minimize costs, I'd like if possible to utilize some sort of peer-to-peer
sync.  In an ideal world, I would only download one copy of the file to one
machine at a given site, and the other machines would then look to the peer
"file server" for the file.   In my ideal, the "file server" would also be
automagically selected, to prevent having to manually designate a machine
that may or may not be online at a given time.

Does anyone know of a script or utility that would assist in this?  The
process would be something like:

1. Site receives request to sync FOO.EXE
2. Check local peers to see if a copy of FOO.EXE is present on the local
network.
3. If yes, copy file from local peers.
4. If no, a file server is "elected" and downloads the file.
5. Remaining machines at site sync from the elected file server.

BitTorrent would be an ideal solution, but we can't it for political and
technical reasons.

Thanks,
Durf
