Good catch, in fact it totally fits with the description of the service as a store and forget for compliance and access only a small subset in the case of retrieval requests — for example when storing customer records. I also must say that the way you calculate the retrieval fee is really looking like black magic at first sight. I hope they will add a simple calculator to evaluate some scenario and provide the expected bandwidth available from Glacier to an EC2 instance.
