It's mesh networking. Convince all client devs to include the samiz library instead of creating a Samiz nostr client please. I notice you only once talk about "Samiz app" in the Readme, so maybe you already see it as an add-on to all Android clients.

I would add the example of a conference using a conference app that uses nostr as its data layer. It would work even if the wifi collapsed and users would have an incentive to install it before the collapse cause conferences do such things.
