Just been looking over my latitude history, and it seems to be off. They're all roughly in the right area (within 100-200m or so), but the accuracy radii shown are far too precise, so clearly something's amiss. It never used to look like this with other updaters.
Incidentally, do you think it'd be worthwhile to get together with the other devs and modularise the service bits of your software, so that we only have one latitude, etc daemon running but used by multiple GUIs? Or even just multiple deamons exporting compatible interfaces so they can all be used interchangeably - UNIX style. Seems like an awful duplication of effort, and it's a pain when I want to use a latitude client to view my friends (which then wants to update my location) whilst zaploc's also trying to update my location, etc....that's all.
