Joshua/Boris:
We tend to use data uploads that just reference a file in S3 instead of
putting the file actually into the repository itself. We then serve the
files from other locations for caching purposes and to make sure we do
not go through tomcat/magnolia for static files. This also allows us to
convert the files into a set of formats on the fly when saving them (all
the resolutions we need) and eliminates the potential for GIFAR Style
(Gif Combined with Jars, potential for all top/bottom reading file
types) attacks [1].

just two notes
a) look at http://www.magnolia-cms.com/onair - it solves these and
many other issues (and allows you to edit video right in your browser)
b) with 4.1 we have "virtualized" the DAM such that the STK
specifically can use pluggable implementations to manage its digital
assets. We ship with support for file upload, DMS and OnAir. I would
love to see a plugin for your setup!

Has anyone tried to set up a system whereby the DMS uses Amazon S3 to
store and serve files?
I have a site that currently uses Magnolia for managing most of it,
but has quite a lot of movie content - the movie files are up to
600mb in size, and need to stream smoothly, hence I currently use
Amazon S3 storage + Cloudfront content delivery network. The solution
works pretty well, but the problem is that there's no way to manage
the movie files from within Magnolia, which makes uploading and
changing movies complex, time consuming and error prone.
Is there any way to change the back end file system used by the DMS
to use S3 (or something similar)?
My idea would be that the DMS would keep metadata about files in the
database, but actually store the files on S3 (perhaps with a local
master copy too, just so that everything is in one place for
migrations etc). When a file was requested it would return the S3 URL
for the file so it would be served directly from Amazon through their
content delivery network.
