The "Oslo" team has opened up their portal, so you can download the "Oslo" SDK and dig in and learn about how the "Oslo" tools work before Don Box's and Chris Anderson's keynote presentation tomorrow.
I just wish that they could have spoken today--it would have livened up a dull session.
p.s. It seems that Chris isn't hosted on Azure--the load is too heavy right now for me to access his blog. Hopefully he'll move it soon.
