lower barrier to entry, access to wider resources at AWS, and being the
recommended delivery format by AWS folks... Also, the general thinking
is that folks who know what they are doing are going to byoi anyway, its
the ones that done we want to help with the AMP.

Also, traditionally, we've never done anything that would be a one way
vendor endorsement, AMP was a way for amazon to acknowledge we exist.

The plan here is to deliver AMP images, and also .raw backing files with
manifests that allow people to either s3 or ebs inject their own images.
I can easily complement that with a public shared image set as well ( we
might need that in some AZ's regardless ). But we'd need to workout some
way to work around cost of doing this. Were looking at a couple of
hundred USD a month.
