BT Live Alternative

So I need an alternative to Bittorrent Live, because it has been and still is in a closed beta for a couple of years now. I need a p2p based streaming program. I am using it to stream content to a small group of people (family members and friends). We used to use livestream pro caster, but it is technically against their terms of service. Anyways I am running on a 5mbps up line and would prefer something like BT live. Something that has a better connection through rate with more people. Because the upstream is shared. Any idea? I plan on broadcasting to like 5 to 15 people at any given time. 

I just checked BT Live and they have stopped development on it. I am curious more than ever if there is a good alternative.

Wow, just wow. A one of a kind piece of software that can revolutionize bandwidth problems with online video is not going to be a thing.

Would Sopcast be a solution? It is p2p, but does it offer better streams with more viewers?
