A workspace for processing media: "Operating table" / "workbench" etc
We have a storage backend that supports multiple media types, but
it's possible that certain types of media might require local files
to be processed through locally. For example, maybe we'll need to
have a local copy of a movie before we do transcoding. Etc.
Maybe it would be helpful to create a BasicFileStorage instance
that writes to a directory either made in /tmp/ or user specified
somewhere else (could default to
./user\_dev/media/operating\_table/ in the config, but if
completely not found in the config, could make a temporary
directory to dump things in?), but which keeps non-permanent copies
of files and local instances that will allow the files to be
"operated" on while moving from the queue\_storage ->
public\_storage during processing.
