Embedding non-public notebooks?

[portokallidis]

Are there any possible or near future workarounds to use the notebook-embedder with non-public notebooks?
Or is something like this planned?

We plan to support PermissionsKey in the embedder library in the future. The "secret" key would still have to be included in the JS code that embeds the notebook. This can be especially useful for non-public websites that want to embed notebooks.

Supporting other non-public notebooks (not via a permissions key) isn't really possible, since we can't rely on the usual (cookie-based) authentication of the viewer (for security/privacy reasons).
