And here is my very simplistic Latitude knockoff...

Petur Longitude

It consists of:

zlatitude.py : replacement file to copy over your existing ZapLoc installation. You will need to edit 67 to enter your server URL

set.php : called by the modded zlatitude.py for checkin, syntax is:
http(s)://my.server.name/set.php?lat=12.345678&long=23.456879&who=MyUserNam e

show.php : called in your browser to show last checkin or location update, syntax is:
http(s)://my.server.name/show.php?who=MyUserName

For every MyUserName that is passed on to set.php, it will create a MyUserName.dat file, so you can have multiple users.

This is a functional but quickly hacked solution that suits my needs (lets my family know where I am so they can guess when I will be home if I'm stuck in traffic or held up somewhere).

Again BIG THANKS to MasterZap for providing the code of ZapLoc so that I could piggyback on his great program!

Enjoy!
