That actually helped a great deal - I hadn't seen that before. On the 
theory that you are open to suggestions, let me share some of the design 
concepts I was coding to.

I was working towards decoupling the primary components. I admit that my 
objectives were a bit aggressive, but not unachievable. I had segmented 
out the back end repository, the O/R mapper, the cache manager, and the 
transaction manager as seperate pluggable modules. One the core JDO 
system was in place, and stable, each of these pieces could then be 
indepednatly enhanced, improved, or replaced, without impact the rest. I 
was also working towards a bytecode enhancer implementation that was 
embeddable in a classsloader.

Let me ask another long term question - is the objective of Sparrow to 
be a quality OSS JDO implementaiton? Or is it, as is the attitude with 
the jBoss group for example, intended to be better than its commercial 
competitors as well?
