MyShowroom.TV: Publish your own live streaming video

MyShowRoom allows people to try broadcasting their own live videos over the internet. Users can create their own web channels and then broadcast live video via a webcam or other means. The service also supports embedding videos into blogs or websites. However, MyShowRoom requires the installation of Silverlight and currently only supports Windows systems. In a sense, MyShowRoom offers a form of video blogging that comes after text and images, enriching the ways people can express themselves. So, how can one make use of the services provided by MyShowRoom?
