I'm the lead on the LiveView Native (LVN) project. Happy to answer any questions here. I'll get a few FAQs out of the way:
* it's not a WebView - we render actual native UI
* we do not push for 100% server-side rendering. An upcoming post will discuss optimistic UI strategies for LVN
* Android support is coming, possibly before EOY
* offline mode is not yet implemented but coming
