      You can share any serial GPS data via third-party COM port virtualization software.  Just let that software "own" the GPS serial port and virtualize it out one (shareable) or more (exclusive) ports for various serial NMEA consuming applications.

      What do you have that will actually consume NMEA data shared over TCP/IP?  And even better, would it be expecting a TCP/IP port to which it will connect or is it offering a TCP/IP port to which the NMEA data source will connect?  In other words, is the requested TCP/IP NMEA-sharing capability supposed to be a server or client port within APRSISCE/32?

      As for Bluetooth, same question applies.  Are you expecting APRSISCE/32 to offer a discoverable SPP (Serial Port Profile) Bluetooth service to which other Bluetooth clients can connect to receive NMEA data (as if APRSISCE/32 was a Bluetooth GPS) or are you expecting APRSISCE/32 to connect outward to an external Bluetooth device (like a Bluetooth to serial adapter) and forward NMEA data out that connection?

      In any of the above cases, there is software out there that does that.  Ever hear of GPSGate?

      PS.  If only the gpsAPI from Windows Mobile had migrated to desktop Windows, sharing a single GPS port would never be an issue.  WinMo includes a virtual, shareable, COMn port offering NMEA data from the platform-supplied native GPS to any and all programs that open the port, concurrently!

      As we have a port to share IS streams I would like a port to allow sharing of GPS data between instances, NMEA over TCP/IP or some such.

      The ability to connect to GPSD would be good or even use it internally.
