I am searching for a self hosted library for live presentations of documents in a browser based on JS. Presented documents like PDFs would get converted to HTML slides. Current slide position (and other properties) should be shared among visitors, so that everyone see the same slide.
Also a blackboard (or whiteboard :) ) would be nice.
So far I have found reveal.js as a tool to draft a presentation as such, but it does not include the server-side configuration which is a must have.
