I am not involved with Stypi but I think the key points from the article are "it wants to let native applications like Photoshop sync changes between multiple users" and that "they’ve laid the groundwork to let other applications sync".

In other words a text editor is one instance of an application that can use the underlying service. Think about that for a second. The concept of collaborative editing as a service that can be adapted to ANY application is HUGE. For example, an engineering CAD app would be more powerful with this feature.

Going further,if you consider that machines can also "collaborate" then it get's even more interesting. An example of human/machine collaboration could be a real-time reporting application.
