'course. Pity Intel didn't think on burning a unique CPU ID into each chip they made. Even PDP11 had this. What can be thought to become a unique FreeBSD machine ID, anyway? I can think on a MD5 checksum of the following things together: CPU type; motherboard chipset ID (if available); manufacturer's ID of a primary HDD; primary disk controller' ID (if available); OS kernel version (?); canonical hostname. And it's hard for me to think about anything else in a PC world that one might depend upon. PC is not a Sun. :( Best, Andrew
