During IIS7 development, I've written quite a few modules for IIS7 / ASP.NET.  Some of these were for various demos, others were to help out various internal and external customers, and others just because they were fun to write. 

Now, I am thinking about upgrading some of these with the feature requests and bugfixes you have been asking for, and getting some new ones up as well.  Come check out what you can get right now, and weigh in on what I should next at http://mvolo.com/blogs/serverside/archive/2007/10/28/Mike_2700_s-IIS7-modules-_2D00_-what_2700_s-coming-next.aspx.
