BTSync is a radical improvement in the network protocols but I still can't get the btsync web ui to change my password. You could say that their priorities are in the right place for an open source project, which they are not.
Don't get me wrong, I love the concept and most of the implementation of btsync. But they are holding themselves back, leaving an opportunity for projects like Pulse.
That said, Pulse is dead in the water without peer-discovery. How do I connect to a peer with Pulse if there is no central server?
