A reply to one of my other threads seemed worthy of its own thread.

If Delta Chat begins adding these other transport options and chatmail becomes just one of the options, you’re basically on the way to building Reticulum from the ground up.

I wanted to nerd out with you all about what a roadmap might look like to moving towards this model.

Delta Chat clients start sending out announces and Chatmail servers start connecting to each other?

Chatmail (IMAP) becomes just one of the transport options on reticulum alongside TCP/IP, Lora, Wifi, etc.

At the core, Reticulum is really quite simple. That’s a major benefit I think. It’s not fancy bloom filters or anything.

And the fact that Delta Chat would have started out with chatmail (something super reliable and functional) as a foundation transport is fantastic.

Anyway, what do you all think?
