A few questions about this project

How is worddocgenerator different from other document generators like FlexDoc?
How do the refreshable components work? Do they connect to the server to fetch data?
How is the performance for generating multiple documents for the same data?
This is a good example of what can be done using the OpenXML SDK – any other useful features that could ideally be added?
