Marc,

It's certainly an eventual possibility.  JDO seems to keep getting decent 
reviews, although until recently, the fact that NOBODY was implementing a 
true JDO provider was setting off alarm bells in my head, which is why I 
haven't studied it in depth yet.  I personally, would like to see the JDO 
tires kicked a bit more before we jump just because if JDO turns out to be 
more of a performance pig (Like Entity Beans), it could essentially kill 
Expresso as a decent performance webapp framework. So given my own time 
constraints, that's why you don't see any significant motion in that 
direction yet.

My first goal with Expresso, however, is to de-couple most of the aspects 
of Expresso so that people can plug in their own persistence where needed, 
be it EJBs, JDO objects, etc.  At that point, if JDO starts looking much 
more interesting than DBObjects, it will be a much less painful process to 
switch over.

If you have any particular JDO resources that you found most useful in 
evaluating the technology, I'd love to hear them.  There are so many JCP 
proposals and counter proposals, that it has been difficult to keep up with 
the 'standards' coming out of there.
