One model I'd love to see is a web based front end, but all video processing happens in the backend.
Then ship the app as a combined front/backend, or just the front end that connects to a remote backend. That backend could be a server in a studio with beefed up specs, or offloaded to the cloud for solo animators working on complex projects.
Seeing a project like this give me hope that we could decouple what the app does, vs how to control the app.
