The first two available webcams, the Microsoft LifeCam VX-6000 and Microsoft LifeCam VX-3000, bring a new dimension to Windows Live Messenger and feature exclusive industry firsts that streamline the webcam experience:

Windows Live Call Button. Located on the top of each LifeCam, the Windows Live Call Button makes placing a video call a breeze by eliminating the usual multiple steps. Just one touch brings up the Buddy Picker, a tool that shows users only current online buddies. They simply select their contact’s name and they are on their way to making a video call.

LifeCam Dashboard. Built right into the Windows Live Messenger window for easy access during video calling, the LifeCam Dashboard provides simple access to the controls people need most, including pan, tilt and zoom. Now users’ attention stays where it should be — on their video conversation.

One-touch blogging. Windows Live Spaces is one of the fastest-growing blog communities in the world, with more than 50 million individual Spaces. Now, users can post High Definition LifeCam pictures directly to their Windows Live Space blog with one click from within the LifeCam window.

This is another one of the product teams I've gotten to work with in recent months. I'm sure you can guess which of the listed bits of Windows Live integration I worked on. By the way, if you are a hardware vendor or into tweaking your hardware you might be interested in http://dev.live.com/hardware/. Building mashups with Windows Live services isn't going to be limited to Web apps, we expect hardware devices to get in on the game as well.

NOTE: MSN Spaces isn't Windows Live Spaces. Yet.
