I'm about two hours late for a vacation, but some quick comments...

I'm kind of hesitant about this. Makes me think of our Spec jars...  
If there are frequent Geronimo releases, how important is this?  
(sorry, i haven't read the previous notes). If Geronimo isn't  
releasing fast enough, I can imagine the hodgepodge of different  
versions -- that ends up confusing us and users... Also, we're  
already coordinating "joint" releases of TranQL, OpenEJB, etc. Isn't  
this adding more?

Are we going to make things easier for a small group, but things  
harder for everyone else?
