Hi Thorsten,
that's a great idea!

`C-a' is bound to `beginning-of-line'.
`C-c a l' is still free.
But wouldn't a property more suitable for the agenda?
* TODO Something in Japan
:PROPERTIES:
:COORDS: gps://35.71083783530009,139.8175048828125
:END:
The `+3km' could be a default setting (and could be supplied as a
filter, just like tags).
(Somehow I see the `org address book' discussion coming up again. Emacs
needs an address book we all use. Something that's delivered with
Emacs.)
Links could point to map.google.com. I'd like to use those links to
store tracks in Org-files as well. HTML-Export could support OSM or
Google-Maps to show the tracks. We also could produce SVGs or PNGs from
the data.

On Linux, BSD and MAC OS X there is `gpsd'. I don't know how useful
it is --- I don't own a GPS yet.
http://gpsd.berlios.de/ states:
gpsd is a service daemon that monitors one or more GPSes or AIS
receivers attached to a host computer through serial or USB ports,
making all data on the location/course/velocity of the sensors
available to be queried on TCP port 2947 of the host computer. With
gpsd, multiple location-aware client applications (such as
navigational and wardriving software) can share access to receivers
without contention or loss of data. Also, gpsd responds to queries
with a format that is substantially easier to parse than the NMEA
0183 emitted by most GPSes.
Is there something like it for other systems? Windows?
I think Cell phone systems should have something ...

I'd make it an independent package. Some laptops come with a built in
GPS these days. And your desktop might know his GEO location as well.
We might have a variable `gps-home-coords' which is nice to have on cell
phones as well (would be great to have several "homes" for some people -
e.g. commuters).
Unfortunately I don't own a GPS yet. But I'm very interested in this
one and surely will contribute.
Best wishes
Sebastian
