Re:One thing I've found missing in FOSS - Geocoder
There is the free http://geocoder.us/ web site that uses the Geo::Coder::US perl module.
The perl module is free software, and the Tiger data that it uses is also free.
The Geocoder.us web site runs this module to do lookups for non-profits for free (commercial use of the web site is not free-but you are welcome to download the code and the data and do it yourself for free).
As a note: The full census data when loaded into Postgis is something like 40 gb, and is dog slow. Refractions is working (or was working) on a pure SQL geocoder. The Geo::Coder::US version uses Berkeley DB files and is about 800 mb.

Re:One thing I've found missing in FOSS
http://geocoder.us/ -- an open source service and cpan module that works off the public domain TIGER dataset. This project also has a module that just parses a US address string into the component parts that you could use along with roads data in a PostreSQL/PostGIS database to do the actual geocoding. Also using PL/Perl in PostgreSQL it is easy to parse the addresses through a set of regular expression searches and an alias table mapping things like R(OA)?D=>RD, AVE?(NUE)=>AVE. etc.
The problem with geocoding is a primarily a data problem not a software problem. It costs a lot to get good roads data like what you get from Navteq or the like. -
Re:people search
I bet you'll see a google map (or satellite photo if that area is covered) with an overlay of where your friends are. It wouldn't be that hard. No, it's not that hard. I've already written code that does it. The tricky part is getting the GPS coordinates for the people, which, thus far, I haven't found a good seamless way of doing. I'm just using geocoder.us at the moment. Doing it via cellphones would be a lot nicer, but I don't really have that capability.

Re:What's my lat and alt?
If you're in the US, try this site: http://geocoder.us/. It a demo of the perl module Geo::Coder::US, available from the CPAN. Pretty hott.
It uses the Census Bureau's TIGER/Line data, which isn't the most reliable for non-urban areas, but it's public domain.
