>From the Amazon web service stanpoint, it woud be idea to have a completely
standaalone package which deploys itself, or the use of a parameter which is
documented here ...
http://docs.amazonwebservices.com/elasticbeanstalk/latest/ug/index.html?using-features.managing.db.htmlwhich
can be used to connect to a persistent  source, like a remote Postgres
DB or the Amazon RDS server. Being able to pass a paramater directly to the
instance could be useful from the AWS stand point.

Will give it a try anyway. Thanks.
