I don't see the problem with cloning to multiple machines either, unless you cloned a machine with static networking configuration. The different MAC addresses should have no effect on the TCP/IP configuration, and if everything is setup to use DHCP (which I assume, on a cluster, you have done) you can push out hostnames and IP addresses via individual MACs to keep static addresses.
Though I'm not sure why you just don't update them over the network instead of using the CDs. You could script the operation and just run it on all nodes
This would appear to be in the wrong forum, as I see no connection with mobile devices here. You should request a moderator moves this topic to a more suitable forum so that your question get's more exposure.
