Example cluster network config scripts for EC2

Hi,
An issue is how to configure the network of master-ami and compute-ami instance nodes given EC2's current network.

The following project seems to have tackled the problem outside of an Globus/Nimbus software stack:
"ElasticWulf: Beowulf cluster run on Amazon EC2"
http://code.google.com/p/elasticwulf/

Discussed initially here:

HTH?
