This post is a little late since the SDK was released about a week ago. At PSC we have been using the Open XML SDK 2 since its earliest beta. It is a very powerful tool for generating documents without using the Office DLLs. It is also the main technology that I have been working with for the last six months. I would suggest giving it a try.
Stay tuned here. In the near future I will be presenting at different locations on this and other document generation technologies.
