Neal, Which application domain are you most interested in? Remember that NuPIC has been used almost exclusively internally by Grok/Numenta until very recently, and so on a limited set of tasks around prediction and anomaly detection the technology are much more mature. In most other areas there haven't been more than tech demos implemented. The kind of extensive use, methodology and rigor it sounds like you're looking for probably won't happen until the code base is a bit cleaner and easier to use. It would be useful to know what you expected NuPIC to be 'doing' so the community can provide entry points and demonstrations that serve the audience you represent.
