Great, and thanks for the prompt reply.
I'm quite comfortable with the shell, so that won't be a problem.
My rationale for purchasing the Neo-n was at least partially so I can implement U2F as one of the multifactor auth options for the
Open Science Framework. Right now we only support Google Authenticator-style TOTP, but I was planning on refactoring that part of the system in the very near future to allow support for other arbitrary options. U2F is new enough that I'll probably also release a Python package to make it easier for others in the future.
