Ian, The recommended way to set up GeoNode in EC2 is to just install the base system to 10.04 LTS and follow the steps here:
http://docs.geonode.org/en/latest/intro/install.html#ubuntu After that, you can do some or all the steps in: http://docs.geonode.org/en/latest/deploy/production.html And create an AMI for yourself for future re-use / abuse :) Most of the things collected in the scripts you pointed to (most of them developed by either Jeffrey or me, or both) have been abstracted into the GeoNode Ubuntu package and added to the docs. I would stay away from those for the time being. If you just want to have the instance dormant and wake it up for high load, I would recommend to stay away from the Small ones that have awful I/O and use either a Medium or High CPU one (64-bit). Another thing we (David, Jeffrey, me) usually do is attach a big EBS in /data and move postgres and geoserver's data directories to it. Andrew Ross recently did this and he may have some notes. About an AMI, I am guessing one will be released some time after the 1.1 release, but my recommendation to create your own still stands. It is not too difficult, albeit time consuming. Good luck with GeoNode on EC2, there is a good part of the GeoNode community that uses the same infrastructure. Ariel.
