I did look up HTTP pipelining before rolling with this, it is severly limited. It can only really do sequential requests concurrencly, not an arbitrary mishmash of requests and replies as ZeroMQ can. Also, pipelining should only do idempotent requests, apparently. My only source for this is the wikipedia article [1] though, do you have some additional info about this?
