The ability to stream live from multiple sources simultaneously, including mobile devices is very useful for our business model of producing events online using social media platforms like Facebook Live or Periscope! I would say it's not as intuitive as other products in this niche, but there are plenty of tutorials available that can help you get up & running quickly if needed.
If your looking into livestreaming options we've used them extensively over the years at my previous job where they were essential tools for reaching out new audiences across many different mediums (digital advertising/marketing).
