Top Level Design

The system will consist of the following parts:

1. Client -- an Applet.
2. Web Server (Apache).
3. Csicq server (written in C).
4. A library supporting ICQ operations (icqlib).
5. A data Base for maintaining lists of authorized users and their contact lists.

These elements have been chosen to enable simple TCP connectivity, quick development and fair server load.

Following is a description of the elements which will be built for the system.
