>Unless the serial number can be read over the internet without authentication As I said in my post below, I just checked mine and the full serial number is included in the device hostname. Since tons of regular PW installs are going to average joe residential sites which will heavily be using crappy outdated ISP provided routers with default passwords and entirely flat unmonitored LANs, possibly with infected machines to boot, it's fair to say that yes in fact the serial number will be able to be read over the internet without any authentication. Anyone who can see hostnames of devices on the LAN can get the whole serial. Although I also doubt any such network will have any real rate limiting or notice any hammering either, and the serials look utterly trivial to brute force. So I'm not sure the fact that they're all broadcast for everyone even ultimately makes much difference.
