IMO talking about API design as the focus is stuck in the past. If the last 20 years has taught us nothing else it has taught us that protocols won the whole http://wiki.c2.com/?ApiVsProtocol debate. No one can argue the complete dominance of HTTP as the dominant RPC mechanism in use today. We should be talking about how we can structure new, higher level protocols on it or create new protocols to improve on it. Not how to replicate all the previous mistakes on HTTP instead of TCP.
