Just updated the client to maintain the connections "forever". If your internet connection disengages and reconnects at a later time, the client will reestablish the connections that you had previously, and streaming would continue as before. With this, you can have permanent connections with family and friends. When you are not conversing, just turn your microphone and webcam off. The other side would do the same. The network bandwidth and CPU usage is minimal in this mode, since there are no active media streams. When you want to start a conversation, just turn on your microphone and call to them. Hopefully, they are there and respond in kind :).
This usage is ideal for mobile devices (smart phones, tablets, netbooks), that can use multiple ways for internet connection (wi-fi, 3g, 4g, etc). Switching between service providers should only cause momentary disruption.
