Ask U of Wisconsin how that worked out for them when Netgear shipped some new boxes.... http://en.wikipedia.org/wiki/NTP_server_misuse_and_abuse#NETGEAR_and_the_University_of_Wisconsin.E2.80.93Madison It's one thing to come up with a solution that works for the 300 (total wild guess) people on this list. But to be useful for field deployable, it really needs to be able to handle a "every Comcast customer in a major metro area", because we *do* want this stuff to work well when this makes it into the CPE that Comcast gives every new customer, right? :)
