Thanks for the positive feedback on the book. If you have any critique of the content, please feel free to post it on the book group list:
http://groups.google.com/group/the-lift-book As for JPA vs JDO I think you should have no problem going either route. I have no experience with JDO, so I can't comment there, but Scala has actually made JPA easier to use due to the availability of mixin traits and some type niceties. If you do go JDO I think we would all love to see any notes, stories, etc about your experience, and we could even build a JDO archetype if there is some scaffolding that would help people using JDO get a Lift app up and running quickly.
