The NIM project founder is sort of a one person show in development and
promotion. I wouldn't say it is not ready for real (commercial) use without
being objective, as you have to really characterize what those requirements
are. If one considers commercial criteria to be something like: toolchain
quality, IDE support, documentation, platform support, sustainable community,
fair licensing terms, significant technical merits, actual adoption in the
enterprise or research community, and commercial support available. I'd agree
that if your graded NIM across these criteria, it doesn't score high. What
impresses me about it are the technical merits, platform support, and its
toolchain.
