Did you simulate network connectivity at all?  Bitcoin is a semi-randomly connected network, where most of the connections are (I would guess) outbound connections from non-generating nodes who are sitting behind firewalls.  With a typical node having 8 random connections, to different /16 networks, it seems to me it would be pretty tough to get tight-enough control over enough network connections to consistently win the "announce a new block" race. @p{par}

Anybody know how to estimate what percentage of connections the cartel would have to control to only lose the announce-a-block race 15% of the time?  It'll be way more than 15%.... @p{par}
