I'm making a client server database app and I'd like the clients to be able
to send messages to each other via UDP multicast.  I'm using
SocketOptionName.ReuseAddress and its allowing me to have each client send
and listen on the one multicast address, but the app is run in
citrix/terminal services (when two instances of the .exe are started on one
box), I get the "only one usage of each socket address is normally
permitted" exception.  Is there any way that I can do this?
