HiveCast is not live yet for public download, but in the meantime think of it this way: A "tuner" or "aggregator". Give the app the url to any Hive-Tube channel or any RSS media feed and it will stream that content to your tv. pc or mobile device and enable you to interact with those streams (livestreams too) in real-time with livechat/commenting, tipping, and upvoting.
Imagine listening to a live radio station and being able to tip a specific song when it comes on the radio and the artist of that song gets your tip in 3 seconds. Or watch your favorite livestreamer on your tv, upvote and/or send him a superchat with Hive or HBD during his/her stream.
The youtube app (for just 1 example), will never let you tune in to streams from other platforms or let you interact with them, let alone getting PAID to do so..
Ok, so wrote a little post about it today right here:
