I’ve been trying to implement a decent RSA-576 factoring client. I’ve uploaded my first attempt at writing a distributed client. This is just a skeleton of a full featured distributed client right now. You can download it here. You have to manually change the starting and ending exponents and run the client on different machines in order to get the distributed effect though, and I don’t have a server written yet to monitor the results (although it will send an email if it finds something interesting!).
