I stumbled upon this post by Allen of Dobeweb.com, where he gives detailed instructions for setting up an EC2 image complete with BlazeDS.  He gets down into the nitty-gritty of running EC2 from the command line (which I haven’t done in a long time… I use the Elasticfox plugin for keypair and instance management) and made it very interesting.
