 My Mono distribution was 2 weeks old...
 Well, I've just checked out the very last
 version of Mono from CVS, but it doesn't
 work at all; I cannot run any Mono app
 (also mcs -v doesn't work - it never
 comes back).

+If sender.exe and receiver.exe are executed on different machines,
+there are no problems at all: I'm able to send and receive unicast,
+multicast, and broadcast datagrams...
+
+But if sender.exe and receiver.exe are excuted on the same machine,
+only unicast datagrams are sent or received, while multicast and
+broadcast datagrams are just ignored (Socket.Poll() always returns
+false).
+
+That's very strange since on my RH9 machine multicast and broadcast
+are enabled...
+
+I hope that helps.

+This works now.
+May be you needed to set the route properly. Something like:
+route add 224.0.0.0 dev eth0
+for multicast.
