PKWe are using it to stream videos… We are using it to stream videos internally for employee training and its better than Vimeo or any other service. This is because it's very good in terms of defining access for videos, which you can choose to be anonymous (through a YouTube-like portal), or organization-wide, or a specific department, or a group or an individual. The interface is also good and we can brand it according to our needs. You can see more by visiting their demo application on kb.vidizmo.com
