Larry,
Actually, I think exactly the opposite is true. I believe NMEA multiplexers could be made using NMEA over TCP/IP on an Ethernet
backbone transparently to the end NMEA device. This technique is used commonly in existing networks today, where the TCP/IP header
is used exclusively for routing purposes and at the endpoint device, the TCP/IP header is stripped and the NMEA sentence is
presented to the NMEA customer bit serial transparently in the normal manner. Similar devices already exist on the market as
Ethernet gateways to RS232/422 devices. Additionally, advanced QOS is available for priority routing if required, preserving the
advantage of manufacturer independence and all the advantages of Ethernet. I personally believe this represents a golden
opportunity.

Meindert, no offense, but he makes NMEA multiplexers. Ethernet would be
the end of that business.
