Just for in one or two years:
:arrow: It would be nice for Kdenlive to integrate an SVN client. Project files would be stored on a server.
:arrow: MLT rendering would occur on a seperate server. Possibly using a rendering farm.
:arrow: Display would be streamed through the internet.
A video editing working in client/server, batch mode or instant rendering.
Don't laugh at me :D
This is the future of team work.
