Why not just use the machine's MAC address?
user=> (defn mac []
(if-let [ni (java.net.NetworkInterface/getByInetAddress
(java.net.InetAddress/getLocalHost))]
(seq (.getHardwareAddress ni))))
#'user/mac
user=> (mac)
(17 148 207 11 74 113)
user=> (do (doseq [m (mac)] (printf "%02x" m)) (println))

Note: only works with Java 6, not Java 5. But it should be unique for
each of your nodes.
