I'd be interested in giving it a try, but doing so would replace existing tools and workflow. As a user, I'm unwilling to do this is I can't both own my data and application hosting.
If Nino doesn't pan out and the product gets shut down, how do I continue to access my now (trigger warning, words used to describe as I understand, not critique) tightly coupled proprietary data? Can I self host? Is source code available? Are document formats open? How do I not get screwed as an enthusiastic adopter in the unhappy case that things don't work out? If I put my data in and the product isn't working for me, how do I get my data out?
