If interested, the backlog is a shared Google Doc we use to track progress of several sub-projects. Yet, we mainly used it as a shared whiteboard but we may formalize things a bit more if others start reading and editing it. Information how to access the backlog can be found here (spot the "Stacktrace Search Engine" sheet):

The implementation we currently present at various Eclipse DemoCamps is almost completely written by him. Thus, he's the "implementation expert" :)

I'm currently finishing my PhD thesis, am involved in teaching, and am in the happy position to advise a great team of 15 students doing theses or hands-ons (have to say this - they are on the list :-)) jointly with Johannes. My major focus is currently on community building, improving the existing parts of Code Recommenders, and pushing towards the "IDE 2.0" vision.

Depending on Johannes workload, he will spent more time on stacktraces if possible. If my writing up is done, things will likely go up to 2-3 days per week and person. I hope this answers your question how much time we plan to spent with this and what experience we bring into the project.

I guess, the result should be checked by you since you also invested a considerable amount of time in representing stacktraces in Scala. Afterwards he will start designing several APIs and server-side services. In the meanwhile, I will spent some time on crawling Eclipse forums to build an initial database for stacktraces just to see whether the concept of crawling forums works as we expect.
