 I would like to see the community come up with an open standard that
 would kill off NMEA.  It could stay purely ascii, be bi-directional,
 easy to use, no binary mumbo-jumbo.  It could be extensible like XML. 
 Best of all it would be free for everyone including manufacturers.

We've had one for years.  It's called TCP/IP and I'm using it to send you 
this message.  Every instrument SHOULD be placed on a STANDARD Ethernet bus 
controlled by a DHCP-enabled router...with wifi would also be nice.
You'll never see it as long as naive boaters will pay through the nose for 
NMEA's archaic nonsense.  You'd have to get them to stop BUYING NMEA's 
member's products to get their attention.  That won't happen.
The cheapest of off-the-shelf routers creates 65,535 ports on each 
instrument and will already handle up to 256 instruments, simultaneously 
without all this 4800 baud nonsense with one talker.  It's time to move 
on...
