- how to upload media to site? somehow make use of Firefogg
- could some of those requests take to long and require callbacks?
TODO:
add fields:
make archive / file link via id?
is extracted field enough or requires frames/video thingy
use api like approach as done in pand.do/ra backend code
cache location, should cache be inside of archive, home folder or whats a good default.
must be a config option in
