Peer-to-Peer Encrypted Messaging
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])
