Custom Conductor (app) to create websocket Signaling server

I was experimenting with the WebRTC connection in Yjs, as used in __holotxt, trying to use a Zome as Signaling server to not rely on external servers.

A signaling server has to distribute a message to other consumers connected over websockets (JS example). The problem of this approach of course is that websocket connections are administered in the Conductor (right?) and are not accessible from the Zome-level.

Would it be possible to handle this on the conductor-level? Would one have to write a custom conductor or does the conductor also provide an SDK or app-layer?
