2017: I guess this project is now abandoned. I got out of the hash cracking scene. I think most of the code is still somehow valid and usable, it just might not be compatible with new hashcat. There was a fork called Hashtopussy which was done by a good team of people, so I encourage you to use it.
Distributed wrapper around oclHashcat
