I wrote an app called NoisePact that makes it simple to tell your neighbors to turn down loud music. I'm not really sure how far I got, but the idea and most of the functionality is there. If you want the source, I'll be happy to give it to you to improve upon (uses code igniter).
It works like this: you sign up, print off an invite sheet, stick it on your neighbor's door. They sign up, and you can login and alert their phone via SMS when it gets too loud. It virtually requires zero human contact, which is nice. But like I said, I'm not sure how far I got this. I did it on a Saturday afternoon to see how much code I could do in one sitting.
