Despite the 8:15am start, there still seemed to be an audience of 75 or so attendees. I put together a deck that talks to the 6 areas of interoperability - namely Network, Data, Programmatic, Process, Identity and Management. I weaved in a demo into each area and finished by building an aggregate service of all the demos and taking it into a single UI - based on the November CTP drop of Avalon.
Here's a quick screenshot of the "final" product (click for full image):
The above shows a carousel control in Avalon, developed by MSR and others in Beijing. Karsten Januszewski (a fellow DPE colleague) and I have been working on extending this, showing how the control can be used in other business applications.
The demo I showed here was for a prototype of a "bill payer" system, where I can see accounts that I have together with a relationship for bills that I need to pay. IMO, the carousel works a little better for more hierarchical structures (personnel directories etc.), but it was a good way of showing Interop with a dynamic UI.
