For the Nostr devs out there is anyone working any of the following:

1. Nostr replacement of email?
I want to ditch my email provider for a functional Nostr implementation.

2. Nostr replacement of text message? Ditch the mobile carriers.

3. Function as both a secure and public git repository. Ditch Github.

If Nostr could do any of these 3, the adoption would sky rocket.
