We have not used RoomZilla as we rather like our Flintstone system for reasons you've heard me go on and on about. That said, I'm interested to see how your trial of roomzilla goes as I'm always looking for solutions that are simple and human focused. Too many things that get "fixed" by technology are worse off then if they were left alone in the first place.
I hear you saying some variation of that in your question here. If you are interested, it may be useful collaboration to work on Nadine together. That's the platform we've been working on quietly at home for years now. Yes, my first paragraph was talking about how I'm skeptical of technology and my second paragraph is talking about the platform we've built. It's not a contradiction if you understand where we are coming from and what we've built.
We've open sourced Nadine from the very beginning so you can pick it up and run with it if you like, but it fails your test of being super easy to setup. I can help with that as I'm looking to finding people who are interested in helping me build it in to a more complete system. If you, or anyone else, is interested, please let me know.
