Best way to extract part of a db and deploy it

Hi,
I'm using MSSQL2k and I have some customers in a customer table. I want to write a webapp and offer them the possibility to teach them using the app while having telephone contact with them. They can use the app on my server for some time and add data to it.
After a while when someone wants to buy the app I would like to distribute the app as an Intranet app to their own server and let them have the data they already have wrote into the db on my server.
Because there will be some customers with much data I'd like some guidance in how to plan the database to easily extract their own data and create a new db polutated with their data.
KennethThe easiest way that comes to mind would be to add some sort ofcustomer identifer to the primary database, and when you're ready toexport, run a script that copies the rows with that customer identiferfrom the primary database to a blank model database specific for thatcustomer.
All you'd have to do is write the script one, and them plug in the customer identifer when you're ready to export.
