If you wander how we can program our own conditional splits in SSIS data flow, or implement our own asynchronous transformations, or implement things such as a Year-To-Date, then you forgot to attend my session at the SQL Server Day. Luckily you can catch up with the slides and code samples on my web page at http://www.u2u.be/res/Nico.aspx#Presentations 
Happy coding!
