Thanks! It only took us three years to realize that just having a
product is not enough, you have to speak about it on every corner :-)
Will do more of this in the future.

I hope we won't. But please speak up whenever you have the ideas of how
to improve Cayenne adoption chances, like the one about the integration
with "lightweight containers".
I personally may have a skewed perspective, and would love to have an
open discussion on the general Cayenne direction. Often when people
come to me with Cayenne questions, they are already sold on the
framework benefits. So I hear a lot of new feature suggestions, but
very little about desired general plan.

We may start this discussion now. I haven't tried Howard's Hivemind
(though I kind of like the name :-)), but I played a lot with Spring,
mostly in the context of Swing applications, not the web stuff.
In the simplest case Cayenne Configuration instance can be configured
as a Spring singleton, and used as a factory for DataContexts. No work
required on our part.
Going further... Don't know if it is a good idea though.. Transparently
binding a DataContext to an HttpSession using Spring instead of Cayenne
web listeners. How would you do this in Spring anyway?
And finally, using Spring transaction management. Lots of people seem
to care about it a lot. I am not one of them since Cayenne transactions
approach is addressing all my needs as it is. But in any event, this is
something that will add value.
