+//! Peer channels for realtime communication in webxdcs.
+//!
+//! We use Iroh as an ephemeral peer channels provider to create direct communication
+//! channels between webxdcs. See [here](https://webxdc.org/docs/spec/joinRealtimeChannel.html) for the webxdc specs.
+//!
+//! Ephemeral channels should be established lazily, to avoid bootstrapping p2p connectivity
+//! when it's not required. Only when a webxdc subscribes to realtime data or when a reatlime message is sent,
+//! the p2p machinery should be started.
+//!
+//! Adding peer channels to webxdc needs upfront negotation of a topic and sharing of public keys so that
+//! nodes can connect to each other. The explicit approach is as follows:
+//!
+//! 1. We introduce a new [GossipTopic](crate::headerdef::HeaderDef::IrohGossipTopic) message header with a random 32-byte TopicId,
+//!    securely generated on the initial webxdc sender's device. This message header is encrypted
+//!    and sent in the same message as the webxdc application.
+//! 2. Whenever `joinRealtimeChannel().setListener()` or `joinRealtimeChannel().send()` is called by the webxdc application,
+//!    we start a routine to establish p2p connectivity and join the gossip swarm with Iroh.
+//! 3. The first step of this routine is to introduce yourself with a regular message containing the `IrohPublicKey`.
+//!    This message contains the users relay-server and public key.
+//!    Direct IP address is not included as this information can be persisted by email providers.
+//! 4. After the announcement, the sending peer joins the gossip swarm with an empty list of peer IDs (as they don't know anyone yet).
+//! 5. Upon receiving an announcement message, other peers store the sender's [NodeAddr] in the database
+//!    (scoped per WebXDC app instance/message-id). The other peers can then join the gossip with `joinRealtimeChannel().setListener()`
+//!    and `joinRealtimeChannel().send()` just like the other peers.
