The good news is that I have rewritten RIPS completely during the past 6 month during my final master thesis at the Ruhr-University Bochum. RIPS 1.0 now uses Abstract Syntax Trees, Control Flow Graphs, and Context-Sensitive String Analysis doing it the academic way ;). The result looks very promising, but its worthless to share any results/numbers without sharing the tool. It is still under development and a release date is unknown, but already in its current state it is way better than RIPS 0.5. In the end, full OOP support is planned. Any updates will be released here or via twitter.
The project continues … =)
