things I hear secondhand of SharePoint 2010

Today I caught lunch with Olufemi Oyekan and he told me that...

1. One may set a time to die (disappear) for documents.
2. SharePoint workflows have event handlers that one may grab ahold of.
3. There are thirty "out of the box web" services.
4. In an ASP.NET app one may specify a SPSite object allowing one to latch onto SharePoint and monkey with it in code:
   SPSite oSiteCollection = new SPSite("YOURNAMEHERE");
