As an alternative to socket.io I'd just throw in SockJS - it may or may not help here, but it seems to be emerging as a good alternative to socket.ioAFAIUI.
On the topic of streaming and HTTP etc I'll also throw http://knolleary.net/2012/04/04/streaming-tweets-to-mqtt/ into the discussion. BTW, Cosm also already supports MQTT, and Nick has done a blog post on that as well recently (albeit direct MQTT connection rather than HTTP-to... which I know Roger has played with in the past) http://knolleary.net/2012/06/08/bridging-mqtt-from-rsmb-to-cosm/ Also: Toby, consider this @mqttorg's official contribution to the discussion =) Andy On Tue, Jun 12, 2012 at 1:53 PM, Dan Fish <[email protected]> wrote: > Hi Toby > > Coincidentally I'm looking into this at the moment.
