How about 3rd party storage through the users own dropbox, gdrive, 1drive. Then it's still sort of self hosted

Also easy to use same data across devices.

Not sure on the syncing strategy/performance

[checker]

Draw.io does storage federation to OneDrive and others pretty well.

i'll have to look into the drive api. If easy enough, this sounds like a plan.
