Good job! Nice to know someone has some of the same problems I do.
BTW, you might be interested in looking at this PASS demo. It has some good ideas.
The SQL 2005 DDL Audit Samples are a collection of sample applications for configuring DDL (Data Definition Language) auditing on one or more SQL Server 2005 instances. These applications were first presented at the PASS 2006 Community Summit in my presentation Building a DDL Audit Solution using SQL Server 2005. They build on top of the Service Broker and Server Event Notification infrastructure available in SQL Server 2005 to provide a means of collecting all server and database DDL events in a central database for viewing and reporting. Full source code is provided for all sample applications to allow you to better understand the technologies and easily build on or modify these samples for use in your environment.
