PixelFlow includes powerful real-time collaboration features for those who work in teams.  

Open the right hand sidebar to see a list of PixelFlow users. The blue chat button indicated the user is online. You can send them a message to open a video or just click on the video they are watching. If the user is not online, they will receive an email or text notification.   

Enable playback sync to share control of the playback transport.  

PixelFlow also supports Skype to help you save on long distance charges.
