At <a href="https://whiteboardparty.com" rel="nofollow">https://whiteboardparty.com</a> we have a closed beta you might be interested in - this is exactly the problem we’re trying to solve.<p>For us, having a living document that survives a video meeting (has an agenda before, supports structured brainstorming, has takeaways that can evolve over time) is the problem to solved after many conversations with distributed teams.
I mourned the loss of the whiteboard when we moved to distributed teams in ~2012 or so. We turned to Google docs and Hangouts, but it's nowhere near the same in terms of flexibility / resolution / efficiency.
