    Sounds good!

    Assuming that we don't attract more machines than we have now, the
    current expectations are
            40% probability of success by late february
            60% probability of success by mid-march
            80% probability of success by early april.

    I'll let Rob answer this. However, you can have a look at
    Certicom's pages (http://www.certicom.com/chal/ch_62.htm)
    to get an idea of the complexity of the next bigger challenges.
