This document discusses a Chrome extension called Geo Messages that allows users to share their location in a peer-to-peer manner when sending messages like emails and SMS. The extension lets users select text in Chrome and click the Geo Messages icon to open a mail client with their text and a signature that includes a link to a mobile map showing their current location. Geo Messages has implementations for Java Cards, JME, mobile web using HTML5, and Android applications, and the new Chrome extension allows location sharing directly from the Chrome browser.
