Maybe there's already such a tool in the open source world? If yes it could be added to Sextante.
For what I understand from a search it seems that other software packages do union multiple vectors in a "cascade": union the first two with the third, the result with the fourth and so on. I would be very handy indeed, but still not sure if it would make more sense to add this feature directly in ftools or in sextante. I vote for the first option and so to move this ticket to the qgis desktop tracker, but obviously Victor has the last word.

- File 10.png added
- Subject changed from "Union" tool that allows more than 2 input files to "Union/Intersect" tools that allows more than 2 input files
Attached a screenshot that shows how the Arc* GUI is made (to allow select more than 2 input files). I guess that under the hood the files are processed in a loop two by two where the result is unioned/intersected with the following input file.
