Think I've addressed each of your notes. I'm planning to make this a series of three tutorials.

1. This one, about non-life processing with the high-level API
2. One about using the high-level API together with Twisted-Web and Jinja2
3. One about using the low-level non-streaming RpcClient API.

If you have any tips of making this a better 'part-one of a series' post, I'm very much open to suggestions.
