+How to check if it doesn't work ?
+
+- java -DIVY_DEBUG fr.dgac.ivy.Probe ...
+
+- check the rendez-vous, either in UDP broadcast or TCP multicast
+  * network available
+  * it works without ivy
+  * it works in ivy-c
+  * it should work in ivy-java
+
+- it should be symetric, whatever the order of the connections ( client A,
+  client B, client C vs A, C, B ... )
+
+- the regexps should function properly, let's build a little testbench
