+1. I am a newbie and have been observing the discussions so far. However it is not clear to me about the requirements. I think a sound approach is to solidify the requirements and then think about the solutions (APIs, the real-time transaction protocol etc).

I agree that IRS isn't going to spring into being fully formed - I expect that we'll focus on a subset of the data-models for sub-interfaces along with an associated protocol (whether that is a new one or extending an existing one).

This is part of where having good use-cases will help us understand what behavior is necessary.
