          I think this is ready for a look. It's pretty simple now - it could maybe be shortened, in fact.

          I was off by a factor of... er... 100... in data volume. It's about 390TB/yr to do naive storage of an Avro Object Container stored per alert (150TB of schema, 240TB of data) uncompressed. This might take a bit more time to think through - that's a lot more than 2.4TB/yr!

          Overall looks good. I have qualms about explicitly defining the Butler as the interface, however. Removing myself from the reviewer list.

          I had a couple minor suggestions but otherwise I think it looks good!
