Andrew Coates has posted a great set of resources on VSTO v3 Deployment, including his PowerPoint deck.  I have recently started to see the value of VSTO and have been talking a lot more about it with my customers.  Hopefully I'll get off my lazy rear and start to blog about it, too. 

I also have the pleasure of being able to speak at TechEd Australia (I will be presenting 3 sessions there on Windows Workflow Foundation).  Hopefully the schedules will align that I'll be able to watch Andrew's talk.
