Cbro,
From your post, it sounds like you are puting your requirements documents and the requirements gateway project on a network server. Then each person can map that network path to a different letter (V: or J: as you described below).
In a quick test that I just ran, if the files the project is referencing are in the same folder or sub folders of the project, it should not matter what the top-level folder is. The test that I ran was to copy an example and all of its files to a new folder on my desktop. Without changing anything, the project opened just fine, and was referencing the new files.
If you are speaking about having the project in a different folder than the documents it is using, then if you open your project in a text editor, you will see the full path to each file. In this case, if the file path changes, you will need to do a find and replace operation to update the file paths.
