This sounds promising.

Is anyone already using Matrix as an event server/queue for interactive environments and/or sensor networks (similar to the Stanford Event Heap [1])?

What is the minimum latency for Synapse/Ruma?

We've done some stuff with sensor networks - eg our FOSDEM 2015 demo was hooking up cars via OBD2 ports to stream their engineering telemetry into Matrix for visualisation/analytics etc: https://archive.fosdem.org/2015/schedule/event/deviot04/

However, this is still fairly PoC. Our latency is deliberately high at the moment (given all events are persisted on all participating servers, and signed etc) - typically around the 100-300ms mark depending on server performance involved. If you want lower latency stuff (eg VoIP or MIDI) the architecture is that you use Matrix to be a signalling layer to negotiate the realtime protocol (eg RTP).
