Sounds like you're involved in a cool project. What kind of
community collaboration/involvement would be helpful to you?
Once, a long, long time ago, I wrote quite a bit of bdb 1.85
code. At that time it WAS the current version :) I might
actually remember a bit if I start working with it again.
But what would be most useful to you?
And if I may ask about a design decision: Why did you choose
a hash structure? Perhaps if you have time you could give
a little more info but whatever fits your schedule.
Good luck on your project.
