We tried various iterations of this when I was a PM a Blue Jeans (enterprise video conferencing company). We always called it the virtual water cooler - a place where people on distributed teams could just pop in and ask questions/chat as people in the office do at the water cooler. Lots of customers showed interest, but nobody ended up actually using it. Video conferences always ended up being scheduled ahead of time (i.e. meetings) or escalated (more like this use case - starting a Slack chat and turning into a call because that was easier for the topic at hand), and this occupied a sort of weird middle ground between the two. I still love the idea, and I hope you can make it work, but I suspect that it's really only ever going to be practical for a small subset of distributed teams that have just the right culture for it (and I don't know exactly what that culture is).
