One of our customers serves north of 1 mio overall provisioned subscribers on two servers with this software, so it's quite scaleable vertically already. It's easier when UDP is used though, because with TLS things add up quite quickly. To

Blue is so facebook, and everybody hates facebook at the moment, so we are grey/yellow for now. Has some potential for pivoting though. And since customer satisfaction is everything, we published our progress on https://twitter.com/doubles
