EDIT: one caveat is that i couldn't distribute the YouTube data so you'd have to create a (free) API key for that part. Luckily it's only ~1 min of hassle.
The "black box" (for me) represents the next update. How can I avoid having to download all the data again and just use the new additions?
Do you have a plan for updates?
It's very likely that your agents can just build the rest, if the backend source isn't provided.
