Here is something I think would be really interesting for the N810. I'm curious what others think. I think the functionality would be reasonably easy to implement, and has some powerful application posibilites.

Basically I'd like to see two things added to something like Maemo Mapper:

1) A method to post current GPS data to an online web service (via SOAP soap or XML-RPC) at some user defined interval. (Maybe X seconds or X change in distance)

2) A method to read/display position from an online web service (again via SOAP or XML-RPC) as some user defined interval.

This would allow for many interesting applications like tracking another person/tablet. A site showing where tablet users are. Etc.

Actually if it was impletement outside of Maemo Mapper, as just a little configurable service, then you could even set it to try and "report" location once a day if connected online in case your device was lost or stolen.

I don't have any experience with Python, GTK, etc. However I could certainly pull together the Web service side of things via PHP.

What do you think?
