multiple application database syncing

I am looking to develop an application which can run on a Windows server 2003 as a service which will periodically update a database by accepting data from other databases/applications at other multiple locations and also send out data when the local database is modified. So that all the databases at multiple locations will be in sync.

The application will need to be able to handle rules/policies for resolving any data change conflicts. As well as allow scalability in terms of additional locations.

The purpose of this project is to minimise internet bandwidth requirement. So the application will need to run on very minimal internet connection as well as sync data using https.

Project must be completed and fully tested within 50 days.

Knowledge of microsoft Sync framework and Symmetric DS will be big bonus.

Please ensure that your bid includes answers to all the questions listed below
Do you have any experience with database sync.
What do you know about sync framework?
Can you explain how you intend to develop this application to syn multiple databases in multiple locations.
How much internet bandwidth do you envisage your application will require to run?

Conflict resolution method (if changes are made to the same entry from more than one location at the same time how will you resolve this conflict when updating database?), internet requirement for syncing the databases (the purpose of this project is so that the internet bandwidth required to run a concurrent database for all the applications will be very minimal).
Also, bearing in mind that the databases will be running at multiple locations.(How would you connect all of them in order to successfully sync, in terms of inserting data and modifying all the databases at once)
How will you handle scalability, in terms of future increase in the number of databases that need to be synced?
You may quote fees above budget if necessary
