I have completed the final pieces of the Logging UI for Vista and posted them on the DownloadCENTER. I've completed functionality to allow you to configure central binary logging, central W3C logging, and site defaults. I've modified the look and feel of some of the pages and I've even added tool tips that show what configuration is being changed with each control.
The source code for this project is also available in C#. If I get a few more moments of time and/or many requests in the next few weeks, I may also port the source to VB.NET and C++/CLI.
In the mean time, if you have any questions, feel free to contact me.
You can find the download containing both the source code and the MSI here: http://www.iis.net/downloads/default.aspx?tabid=34&g=6&i=1328
