I can't get any of the links to work either Jim. I even tried going back to my original search page and accessing the site from there, but no luck.
I looked in 2 of my nursery catalogs (Raintree Nursery from Washington and Edible Landscaping not far from me here in Virginia) and both had blueberry varieties reputed to be hardy in
zone 9. Edible Landscaping even had 3 varieties they said were hardy to
zone 10.
Both nurseries had two varieties of Southern Highbush (Mistyblue and Sunshine Blue) that were low chill. Edible says 200 chill hours and Raintree says 150. They're
zone 9 according to Raintree, but
zone 10 according to Edible Landscaping.
Try talking to extension agent in your area to see how many chill hours you get.
