zenquest writes "SecurityFocus reports in this article that a recently-enacted Michigan law makes the graduate work of Niels Provos illegal. (His honeyd project was discussed here a few months back.) According to the article, "Among other things, residents of the Great Lakes State can no longer knowingly "assemble, develop, manufacture, possess, deliver, offer to deliver, or advertise" any device or software that conceals "the existence or place of origin or destination of any telecommunications service." It's also a crime to provide written instructions on creating such a device or program. Violators face up to four years in prison." Provos has had to move his website and research papers to a server in the Netherlands. Similar bills are under consideration in seven states, and have become law in six others. The EFF has more information about the individual states. So, does this mean that Caller-ID block now illegal, as well?"
