RC5-72 project of distributed.net (where we get our work from) announced a while back that they had completed 2% of the keyspace we are checking. They also calculated that there's still more work for 9 to 137 years so we don't have to worry about running out work just yet.

For the announcement itself, please read http://blogs.distributed.net/2011/11/27/18/26/bovine/.

Thanks for crunching, keep it up! :) How about we try to push the time to get to 3% under a year? With your help, we can do it!
