If your system can suffer from DoS because of a single person making single connection once in 2 minutes, imagine what happens, if someone will poll your system from a small botnet (like 100 servers) via random proxies making 10-100 connections per second each. Just for fun.

By the way, binkd can handle multiple connections simultaneously, so I can't really imagine how a single node can cause DoS by polling your system every 2 minutes.
