Description
For E2E encryption we need to publish events to multiple subscribers, there may be multiple strategies but the one that I am investigating is to publish N times by using PublishOptions(eligible=recipient_session_id). How the session ID is discovered is a separate thing.
One thing that is currently missing in autobahn is to have a way to specify which responder_pub to use when an event is being published. Once it supports that, any helper function like publish_bulk(topic, [recipients...]) could be used to achieve the 1:N publishing.

Research direction
Start by tracing the PublishOptions(eligible=recipient_session_id) publishing path and the existing responder_pub handling. Determine how a publisher can select the responder_pub for each event, then verify that repeated publication can target multiple recipients; session ID discovery is explicitly outside this issue.
