vB Module for adding Custom Searchable Databases seperate from main DB

[Quarterbore]

I am trying to start work on a new Mod and before I get to far I would like advise if such a Mod exists... Following is a list of basic features that I want to incorporate:

Create a Module or Area within the vB Admin Area that would allow a board Admin to establish new tables, or fields... define attributes... and perhaps design queries that would be run on the database and shown to members.

• Integrate vBs user permissions and user groups to control access to these pages through sessions and access rights...
  
• Allow Admin, Moderators and poster power to delete or modify while other members would be read only...
  
• Allow some fields to be public while others would be private...
  
• Integrate Cron to purge or Archive older data

Following is a list of databases that I want to integrate and I am planning to do these in a seperate database from my main vB database to keep my vB database as small as possible as I am expecting some of my additional databases to get huge.

1. CLASSIFIEDS DATABASE!!!
2. Reviews Database
3. Contacts and/or Member Lists

Please advise if anything like this exists and if anybody is interested in helping me with this project... I am learning my way around the code so if some of the better coders here are interested in working with me I can provide us with a home on one of my websites to work on this...
