I missed the announcement last week but it looks like Microsoft will be offering paid support for a longer period of time for some products. You can read the announcement at http://www.microsoft.com/presspass/press/2006/aug06/08-28CSAProgramPR.mspx. It is very light on details (such as how much the program will cost and what will be covered) but if you have that one application that will only run on a previous version of the OS it might be woth a look.
