I'm a bit worried here that a sensible, small, limited and easily
implementable piece of work (stream events to tenants) is trying to morph
into 'lets re-write nova' - can we keep the two separate, please? Maybe
start a new thread on the pros and cons of moving away from the current RPC
model (which I'd love to hear - I don't see what's wrong with what we have,
but that probably just means I don't understand what you're proposing)...
