Some things I noticed:

* Use … Reply by tinstaafl

@N, TCP only? You're headed towards a small disaster. I can't know what product you are using and if your device's coder learned about this and took steps to mitigate it. We went UDP and our own protocol to competely avoid that issue plus drop communication costs.
