An Application for Small to Medium Scale Intra-Group Communication

2. Operational Concepts
Message Boxes are like small-scale private newsgroups.
They will be used by smaller groups (10 to 50) to share short messages more efficiently than with traditional 2-way communication.
Message Boxes will be secure. No unauthorized access.

3. System Requirements
To the right are some samples of what the message navigation tools might look like on the phone.
The application must be simple, so most of the interface will be through select screens.

4. System Architecture [Midlet] -- [HTTPS/TCP/IP] -- [Servlet]
Servlet does not need any information from a third party.
Servlet keeps track of the boxes and presents them in browser-accessible form.
Midlet sends requests, parses return information, and displays the messages.

5. Lifecycle Evaluation
Need skilled server-side support throughout the life of the project for maintenance and security.
Need to form dedicated user base to generate necessary network effect required for the adoption of the technology.
If these are in place, then continued project success is likely after product shipment.

6. Feasibility Rationale
Most of the development shouldn’t be hard.
The basic Message Box technology is an extension of earlier cycles in class.
However, the SSL transmission facility will not be supported by Sun until v2.0.
Therefore, the project should wait until this new tool is available.
