It's not hard for IRC-style chats, but it gets harder if you want to handle:

* Asynchronous messaging: what if the two devices are not online at the same time, or on disjointed networks? Store the message on a server somewhere? Secure Scuttlebutt[1] relies on devices pulling encrypted data that does not belong to them.

* NAT or firewall hole-punching, though it can be remediated by leveraging other nodes. Some implementations use a DHT[2], but you're often relying on other servers of some sort.

* What you call contact discovery is also typically handled through a DHT of some kind. Yggdrasil-like (or hyperboria, cjdns, .onion) overlay networks are usually able to route to a public key, regardless of how it moves around on the network.

* Push notifications. Either you accept the use of an external server (like the Tox client TRIfA, which has an add-on[3])

On-device bridging works like this https://blog.beeper.com/p/how-beeper-mini-works. We'll put together a full technical deep dive for the real launch, this is just an open beta. Our signal bridge code is open source: https://github.com/mautrix/signal

You don't have to use our hosted bridges, we've made it ridiculously easy to self host: https://github.com/beeper/bridge-manager

Exactly yeah, I used this bridge with this playbook

I personally recommend going with a Matrix client and building a bridge to your Signal account.

OWS has historically been hostile to third party implementations outside of their clients. There are multiple unofficial options but the only one I've been looking at is the bridge with matrix, though setting up a matrix server just for this is likely overkill.

However, looking at the Matrix docs for the mautrix-signal bridge, it seems to be open-source and end-to-end encrypted. You'll have to look through the source code to figure out how they did that, I guess, because I couldn't find any details.

Once you have the home server set up and configured (not covered here because it's a process), clone the bridge repo (for instance mautrix-signal and follow the instructions.
