.com.unity Forums - Online services for mod collaboraton?

So here is a basic plan I have... Discuss!

<u>Online Mod Collaboration Project Outline</u>

Overview

Create an online system for collaboration in developing mods for SE4. Can be expanded to other games, such as SE5.
Will support many mods. Possibly include a basic forum for each mod for discussions.
Support rolling back to previous versions of items.
Exportable data to an actual mod installable into SE4.

Database Schema

Users Tables
users table will store information on registered users.
users_permissions table will store information on which mods users have permissions on.

Each mod will have its own set of tables to make access and maintenence easier. Based on codebase of Adamant Mod Database.
modname_details will store basic information on the mod project.
modname_news will store mod project news.
modname_filename will store data on the items specific to the filename data file. Will store all versions of an item for history of changes purposes. Each item will have parent pointer pointing to the item it is a new version of and a child pointer pointing to the item that replaces it when a new version of the item is uploaded. Latest version is determined by null child pointer.
modname_forums will be several tables for discussion forums.

Permissions
