I think that some people get excited about companies that employ gadgets that remotely resemble Nunchi, in particular, because they do not fully understand what Nunchi can do--that is not to say that I understand fully what it can do either. To me Micro Signet is a much more straight forward concept. As for Nunchi and Micro Signet they will be dead in the water until they are not, which could happen any day. That said, the longer they go without a license announcement the concern does increase as to their viability.
