host the book on ReadTheDocs
It would be really nice to have an always-up-to-date hosted version of the book. This would be possible using ReadTheDocs, their only requirement is to have the source files stored in a "docs" folder.
I did a test on a fork, and the only things to do to make this possible would be basically to rename the "src" folder to "docs", and enable the ReadTheDocs post-commit hook in the repo's admin page.
You can have a look at the result from my fork here: http://python-3-patterns-idioms-test.rtfd.org/
