The ownership rights thing could get hairy, but something we could always sign away. After all, this game is expected to be in alpha for an extremely long time, and I don't think anyone is doing modding or utility designing with the hope or expectation of monetary reward.
Here is one of the reasons I made this post:
At the beginning of the summer I decided to start teaching myself perl (later changed my mind to python), and partially inspired by DF, I decided to try to make a mythology generator, which would ideally create an interesting mythology with several actors, important relationships, legendary events and locations, etc. If it went well, I was considering making a basic game where you could control a diety, and (indirectly), its followers.
I'm not very clear on exactly how Toady has set up the myth generation in DF, but I was thinking that if the DF community asked him what kind of thematic and practical attributes and constraints he wanted on it, the DF community could maybe make a mythgen for DF. If the result was approved by Toady, it could be incorporated in a later release. It would also probably be good because at the moment, the religion system isn't very developed, so it would be fairly east to add on right now. Then, Toady would be able to fairly easily add religious events into engravings and decorations, mythic locations, and other features based on the world's myth system.
It's something that would probably work well with crowdsourcing, because while it would require coding, the majority of the work would be coming up with a complex flowchart of potential events, and as many different ways to describe events as possible (to make every event as unique as possible). It would also be a way to tap into the enthusiasm of DF fans who don't have much programming/modding experience.
What does everyone think of this? And what is the appropriate way to approach Toady about this?
