Is this really true? I noted a reference to NEMA 2000 certification in
the link posted by the OP. What are the terms of this certification?

I haven't read the actual spec, since it costs money, but I was under
the impression that there are no extra licensing fees. If you want to be
sure, you'd better ask the NMEA folks themselves. Getting one's product
officially certified probably incurs some costs anyway.
