Hi,
I finally got
this one online. John wrote it in 2006 and offered me to publish it on my site. However, he never really found the time to check the (minimally) revised text, so it stuck in my computer for 7 years. As he himself seemed to be interested to get it out, one week ago I decided to make it accessible and told him to leave it there unless he protested. We are definitely on friendly terms with each other, and this came out in a mail correspondence.
