Facebook Applet Needed

What I need done: I need to develop a "mini" application to put into facebook, twitter, myspace, etc (in that order). We are a location based service which members use their GPS phone or GPS device to track themsleves, loved ones and share their location information. You can see more at livecontacts.com. If you've heard of loopt we are very similar. Livecontacts allows users to share their current location with their trusted contacts as well as see the location of their trusted contacts. Applet Features would include a map, buddy list and location of self and buddies, both visually on the map and on the buddy list. When facebook member is in their profile they would have access to a “full” version which includes features mentioned. When their connections/friends view the users profile, only the location of user should be seen on a mini map with high level address (city, state, country)—buddies location should not be shown Within the application users should be able to easily share location with a friend, ask friend to join and export location “badge” to personal website/blog Timeframe of delivery: I'd like to have this live within the next 3-4 weeks
