What I want is for the iPad to be the multi-display for Speakeasy's network which can be viewed at the nav station, helm, and bunk. Not just viewed, but used to interact with network systems. That requires an onboard network that casts NMEA over WiFi (Bluetooth, Wireless USB, etc.).
As Brian puts it "The plan is to support NMEA-2000 over TCP/IP via MacENC to iNavX just as now is done with NMEA-0183. The Actisense Gateway will be interfaced to the Mac and MacENC will broadcast the NMEA info. And of course iNavX will support the larger iPad touch screen."
I have some network updates to make before I can test my iPhone or the iPad when it ships.
