Most PWs have an "owner", and perhaps a team of developers, or more likely these days a few select individuals who have access to the module and it's files, and the secrets of development are closely guarded.
For a long time I have been interested in a completely open source, and truly community project. I became one of these "owners" a little over 3 years ago, after having been involved with the world as a player, and later content contributor, for over 9 years. And even though, I implemented many systems (for lack of a better word) to make it even more of a community project, I was not able to achieve that which first got me interested, and then later hooked (for over 12 years now) in this game, and more specifically the world I have been involved with. That being, it being a truly community project.
But now as we are transitioning into a new phase of our worlds existence, this is the one thing I really wanted to implement. And as such, I have made the module files available to our community, and to the greater NWN1 community.
My hope is that doing this will foster a new era for our world, based on community ownership and responsibility, and also set a precident that this is a viable concept for a PW in NWN (and internet gaming in general.)
If this concept interests you, or you simply want to check out some of the modifications we have made, perhaps to incorporate into your own world (please give us credit at least if you do though), I encourage you to do so. It is hosted in a cloud with instructions here:

It's pretty risky considering what we are giving up by doing this, but at the same time what would an experiment be without some risk? And what is the point if a dream can not be achieved?
