This must be SharePoint tools week. I missed the announcement! 
“Not sure about other people, but I find it quite time consuming when trying to manage users inside of Windows SharePoint Services sites, especially when the sites in the hierarchy have their security inheritance broken. A number of customers end up breaking security inheritance at every opportunity and then hit this problem.
So, I am in the process of writing a SharePoint User Manager Windows Application in order to help out in this area!”
