+many destinations on a LAN.  This can for instance be used to install entire
+classrooms of PC's at once.  The advantage of UDPcast over using other
+methods (nfs, ftp, whatever) is that UDPcast uses UDP's multicast abilities:
+it won't take longer to install 15 machines than it would to install just 2.")
