I shared some of our experiences with financial services industry implementations in a 90 min webcast. I touched on 5 distinct scenarios where SQL Server 2005 may help financial services partners and customers.
  - Cost: full lifecycle of a solution - Development, deployment and maintenance
  - Regulations and Compliance issues - How does SQL Server 2005 help you comply with Sarbanes-Oxley, AMI, BASEL II etc.
  - Data and Information integration - Access to many data formats and data system from within SQL Server.
  - Business Continuity and Reliability - Low cost High Availability
  - Scalability and Performance
