What I'll be doing is a series of posts on Ruby Inside which cover much (but not all) of the material on a topic by topic basis and then, eventually, include an e-book version for free with the screencast product (for existing customers too). So in the long term, yes.

However, in the interim.. I've put up the notes I used to make the screencast as a text file at http://rubyinside.com/19.txt - it's also pretty unwieldy but is text, at least ;-)
