Livestream have announced the Mevo Plan which allows you to stream to multiple destinations at the same time including YouTube, Facebook Live, Periscope (Twitter) and Twitch - there are a few restrictions such as Facebook which won't allow you to stream to multiple destinations other than Livestream. Regardless of this the Mevo plan sounds pretty cool.
From $10/month (USD) it seems like pretty good value if you are doing regular streams and have the need to stream to multiple destinations simultaneously allowing you to increase your audience reach.
