Grok *aims* to support reusing bits of it. It hasn't reached this goal 
yet as we focused on making it work first, but has been an explicit 
seocndary goal from the beginning last year.

We need to do some things to make this possible:

* Done: Grok's mechanism of scanning for classes and instances in 
modules and issuing some form of configuration has been factored out 
into the martian library.

* as Philipp mentioned, emit configuration actions instead of component 
registrations directly. This is underway, started at the sprint last 
week by Godefroid Chapelle.

* split up Grok into separate components that are independently 
reusable, without having to pull in the whole of Grok to use this. 
Philipp wanted to start this work but I'm not sure about its status.

* related to this, Grok turns off some of Zope 3's security 
infrastructure (for content objects, not for views). The Grok core 
should continue doing this for the forseeable future, but of course if 
you want to reuse other bits of Grok standalone this shouldn't come along.

So, this is slowly but surely coming nearer. We want Grok to be a 
unified story for most users, so this is not our *primary* goal, but we 
do want Grok's work to be reusable in other Zope 3 projects as well.
