I think you are right actually. I will experiment with some ways to make blocking vs non-blocking operations. I need to try out @paulddraper's suggestion below to see if I can do that over http. I'd like to make a raw socket version regardless. Like you said, I just need to figure out the best way to pass the key. Edit: One nice thing about the https interface is that you get an encrypted channel. Maybe SSH would be another option for transport. That would also make passing keys easier.
