So far we have no real structurized ideas how we would like to handle all this
nice location opportunities aside GPS. Stuff like

- timezone from GPS coordinates
- City from GSM cell
- ...

are just small things we could offer applications this way.

If you, and other interested people, would come up with ideas for how we should
handle this in FSO that would be great. From our side I fear not much will come
before the MS5 milestone.
