I came across nodered.org it is everything I hoped the planner could of been!
It comes from the team at IBM UK who have pedigree as the home of MQTT.
I liked the planner as it gave non-coders/makers an easy way in to the imp to do neat things.
Will be very easy to expose and agent end point to node-Red. Given all the modules in node and easy way to create new nodes in Red seems like a good way of integrating things. When I get time will give it a go and report back. Thinking of using MQTT for inter-agent-imp coms.
