[Bf-committers] new idea: production information

So the plan would be to display metadata in a web based filebrowser? I can
see how it would be useful for render farms. You could probably do the same
thing through scripting an ftp client or update blenders file browser to
have network access. Thumbnails and versioning support would be useful too.

In a second note.. a render farm with a central file server and blender
supporting block level network lazy loading would be sweet.
