It somewhat overstates the severity of the issue with TCP and the dynamicism of the underlying network topology... Although that's often brought up by people who've never used anycast before and think they're being clever, in actual deployed networks it's accounted for less than 0.001% of total traffic volume, or far less than is generally lost across the network anyway. It also describes the group-membership-announcement issue, which is basically a non-issue now that all the host vendors can support OSPF, which neatly fills the need. -Bill
