We're using nats for synchronous communication, sending around 10k messages each second through it. Must say that the stability is great, even with larger payloads (over 10MB in size). We're running it in production for couple of weeks now and haven't had any issues. The main limitation is that there is no federation and massive clustering. You can have a pretty robust cluster, but each node can only forward once, which is limiting.
