I don't think there is a technological silver bullet, but technology might enable you to overcome your concerns. Reading other answers and your comments, one concern seems to be the inability to influence mods once they are in their post. That seems easy enough to address through community voting implemented and enforced by the software.
What your really need to do is sit down and game out the situations and actions you need, and that becomes the basis for your functional software spec.
The bigger issue is who runs the software and on what hardware? Implementing safeguards to keep server admins in line with the community would be much more difficult than mods.
