Flash project with network communication.

I need a simple program in Adobe Flash/AIR that will communicate over network it can by using database or XML shared on web server. What I need is a program that will allow 3 functions: 1. Will get some serieal id ID from a device I run it on and automatically create account for it. 2. Will allow user to select what Blood group he has and will store that info in the database - also will rememnber email and phone (one of it will be necessary to be filled in). Also a area of a country is requred to be filled in. 3. Will allow user to notify that he needs some group of blood from a specific area. When he does it a notifacion is send to applications of the people in his area that have the same blood - in notification message they have also contact info to the person in need.
