Great interview GCN, you did it well

A few questions for Brian if he pops up again:
- Do you feel limited by what Microsoft's other applications support? For example, nearly every app in OSX (iCal, iTunes...etc) has scripting support, so its easy to integrate those into their (technically similar) gadgets, but things like Windows Calendar have less flexible (if any) scripting support. For WinCal, for instance, there is no API at all. How far do you see this becoming a problem as the sidebar progresses?
- Will Microsoft be commmited to new sidebar releases, even between Vista upgrades? So, like Windows Defender can update its engine, the Sidebar can update its object model (compatibility ensured through the manifests). Updates distributed through Windows Update or things like that, to address developer's concerns and add object model features would be a real boost for Sidebar adoption. For example, if WPF support could be added through an update.
- Will the sidebar ever become resizable?
Also, I'd like to add that, for the questions about DWM and WPF integration: its (sort of) already there. It always has been. DWM is composited by the same 3D, vector-based engine that WPF is (MIL). WPF is just a way for developers to write applications using that engine. DWM is (and always has been) driven by a 3D, vector based compositor and rendering engine. The reason it renders PNG files for window frames isn't because the technology isn't there: it's that they're not using it to draw vectors.
It's like a door: the hinges are there for both pushing and pulling. Just because I'm pushing right now, it doesn't mean the hinges limit me pulling the door: at any point, I could change what I'm doing, and pull it, and the hinges always supported it.
