That looks really cool, will see if we can add compatibility. Don't have that behavior yet albeit it does pack a NOSTR relay. In geogram there is the concept of "postcard", which is basically a signed note which can cross multiple stations using whatever methods until delivered to destination. The main difference when compared to that method is that you can see the whole provenance (who was carrying the message, under which method) and able to reward those people upon receipt of delivery:

This was made for cases of no-internet when someone has costs to physically carry your messages and bring replies. Replicating what is done today around the world, just in a digital format. > Is it possible to connect it with bitchat or tollgate? Never looked into this. Can later add compatibility.
