A friend just asked me "is there any transparent CORBAlike product for python?" Now, I know there is, but I couldn't recall details. So I poked at the PyPI browse interface... "Software Development" ... "Object Brokering" and there's the list of tools.
Neat.
I still need to think of a way to address the issue of people not hiding releases... Maybe I should alter the code so it auto-hides un-hidden releases when you add a new one. The single-visible-release use-case is probably the more common one...
