..actually something pretty silly. I had used
Http://...... instead of
http://... The ipod input keys automatically capitalise the first letter and I hadn't noticed.
I also found that if I used
http://mymac.local:8080/stanza it listed "stanza" as a book. If I used
http://mymac.local:8080/ it listed my book.
Anyway, upshot is I can download. Now I just need to check out the formatting of the converted PDF.
