I do see that this thread was created in 2011, and probably longer relevant towards the current Satoshi Client; I would still like to thank you for your efforts in closing the gap between developers and users. I have been picking apart some of the older clients as well and with the way the code is laid out, it can quickly become overwhelming. Although my findings were similar to yours, it was a pleasurable read that helped me evaluate my findings with a better since of clarity.
