I worked on Proba-3 for a while. The original goal of the project was to demonstrate formation flying in preparation for another telescope (I forgot the name, but it was something like Xeus). That telescope would have a camera and lens on seperate spacecraft, and the idea was that by moving the lens backwards or forwards you'd be able to create a much bigger telescope than could be built with a single spacecraft. Unfortunately that telescope was cancelled, so although Proba-3 is still demonstrating a cool technology, it probably won't be applied elsewhere for a while.
