Do you mean that your earthmate doesn't work with gpsd anymore?

Gpsd is an option (the code is there), but we can't open a tcp connection to localhost because there is no loopback network device, and because the disks are not writable a named pipe or unix domain socket is probably hard to do as well.

But plugging the earthmate protocol from gpsd into gpsapp should be pretty simple, it might even be easier than it was to add it to gpsd in the first place
