If I am correct, all of these products only offer a serial point to
point connection over ethernet, which seems quite pointless to me when
you want to distribute NMEA from instruments to ANY device on the net.

If I sold NMEA multiplexers, I wouldn't see any point to Ethernet or
TCP/IP
either....(c;]

Oh I do. There is a market for multiplexers that collect NMEA from various
devices and distributes it over ethernet to several computer systems on
board of larger vessels. Preferably with the possibility of converting
certain NMEA data into Modbus for use on the numerous PLC systems on the
same vessels.
