Hi Abmar, cool project! I wrote an implementation of the Phi Accrual Detector which I would be happy to donate. It has the nice property that its parameters are based on expectation odds rather than something more arbitrary like # retries.
You can steal it at http://github.com/arosien/failure. It works well but let me know if you have any suggestions. ..
