Obviously it makes sense for you to hold 1 version of your calendar. Multiple versions of a live document is bad.

Therefore… Ideally this calendar information would be hosted by a native client app. Ie it’s my information and it lives on my phone.

It lives in an app that can receive pull/push requests.

Having Google own your calendar, and data mine you is not great.

Not my entire calendar should be visible across nostr, but I should be able to create calendar timeslots and sell them over nostr through my bio.

This is the kind of new functionality that can be built into this kind of many-to-many social media. With hard money integration.
