Outlook Calendar and Contacts Sync Over Internet- PC to PC

This project is to develop a small, lightweight Outlook Calendar and Contacts Syncing program that will work over the Internet from PC to PC. The program requirements will be as follows: Client side: - Must be able to sync all current versions of Outlook Calendar and Contacts with another PC running the client through the same account. - Must have user accounts and passwords setup, where in all users under the same account can sync with each other. - Must have call home to the server to check account status, and have the ability to enable or disable the software from the server. - Must include a 15 day trial, after the trial the user can be directed to our website to purchased and software will be disabled. - Must be small, and light on memory and cpu usage. - Must automatically sync without user actions once setup, this can be real time or in 10 minute intervals. - User should be able to choose which Calendar they would like synced if they have multiple calendars. - Must work through antivirus software and firewalls without the need for port forwarding. - The GUI can be small, but must look professional. - Must be compatible with Windows XP and all higher versions. - We are open to ideas on how the sync itself would work, either P2P or through our server. Server side: - Server database must use MySQL. - Database should contain account, password, account status, purchase date, license expiration. - Users contacts and database can be stored on the sever if needed (open to ideas). **The above is only a general guide, we will be discussing the project with you in detail and get your feedback/ suggestions.
