I have not seen that many WCF or Vista peer-to-peer applications, but they are both incredibly powerful it would seem. The distributed demo that Mike Taulty showed was very simple and yet showed off the power of using the foundation. If these WF & WCF demos are at the same level as the WPF ones (which I know were just the tip of the iceberg) then there is a fantastic amount of potential in them. The day’s over at Microsoft but we are now off to bar revolution for the start of the geek dinner!
