I don't have mr_jrt's problems, but I do have a request.
Could more options for shorter update periods be added? 5 minutes is now the minimum, but I often don't find that enough. 2 minutes or perhaps also 1 minute would be much appreciated.

I'd fix this myself but unfortunately the so-called source package only contains compiled python files. I also wanted to add a filter for updates, as when I'm home about 50% of the updates say I'm at a house 150 meters away. (There's no cell tower there!), In the old zaps-new-latitude-updater.py I had hacked in some code to filter such updates, but that script doesn't handle the new oauth authentication to Google
