The SQL Server Metadata-Driven ETL Studio (MDDE) was an internal MSIT project first shown at the MS BI Conference last year. The http://www.codeplex.com/SQLServerMDDEStudio . There isn't much information up about it yet, but I'm told that docs and examples should be appearing soon.
Essentially what MDDE gives you is a way to create SSIS package templates, which can be easily updated when your metadata changes. I'm currently playing around the code, and will hopefully have a walk-through up in the next little while.
