If MacGPS Pro can access GPSd, and you write code to implement GPSd, you COULD think about GPSD reading the netstumbler input rather than the GPS device (e.g. if no device is available or by whatever criterion) and use that for GPSd output... Or is this a silly thought? Will GPSd be a true daemon and (hence?) be faceless, or is it an application with a GUI front end, or maybe a preference pane? Ard
