There is one, and it is a very powerful and mature.

Or so I have been told by my good friend and coworker Eric Barroca.

It's called OSGi (http://www.osgi.org/)

It is used for set top boxes applications provisionning, as well as for
assembling components in the Eclipse platform (including Eclipse RCP)
which, according to another good friend and coworker (Julien Anguenot)
shares some similarities with the Zope 3 component architecture.
