Screenhero is a newly released tool for collaborative screen sharing between two (and more later) people. Each person can move around the shared screen independently of the other people, and make changes and edits as required.

“Once you take that simple step, that’s it: you then have another mouse/cursor appearing on whatever it is that you have selected to share. That person can then effectively use that window at the same time, and in the same way, as you do.

So, for example, if you shared an open Word document, the other person could start typing, erasing scrolling and printing that document, as if that document existed on the remote computer. And, like a little mouse, you can chase after the second person undoing all the changes. Similarly, sharing a full screen lets a person access your whole desktop in the same way, but across the whole range of apps that you may have open at the time.

Screenhero’s approach, which uses Google’s VP8 video compression standard and WebRTC for network transmission, is in contrast to other existing solutions like Skype, GoToMeeting, Join.me and Google Hangouts, which variously require you to pass control to another user, or somehow both be able to use a single mouse at the same time.“

Available immediately for Apple Macs. A Windows version is in the works. The company is considering its options for post-PC devices.
