As a member of a totally distributed UX team, yes. We've been looking for just a simple whiteboarding tool that updates live, supports a pen tablet, and lets us collaborate around any rough UI language. We haven't found any that have stuck. This has the potential (haven't used it much yet) to enable us to quickly sketch UX concepts at early stages collaboratively, which is huge. We don't do real mockups that are persistent and used as a base for development anyway—it goes straight from paper sketches to HTML prototype. So this fills a real hole, just rough enough to work together on, just high fidelity enough to make sense to others. Side note, "mockup" is such an ambiguous and relatively irrelevant term for whatever happens at this stage. A mockup here is just whatever you need to visually communicate the UI. The simpler and more malleable the better. If everyone understands the concept and how it translates to a UI in your application framework, then the process was successful.
