Paper on Creative Commons licences and warranties

For those who are interested, I've made a PDF version of the paper on Creative Commons licences and warranty issues which I referred to in previous postings.  It's an assessment paper and consequently wasn't written to the same standard as it would have been if it was for publication.  The paper also had to comply with a word limit, so its treatment of some areas is necessarily superficial.  I'd be interested in reader's comments.
