Sure, I agree that's a desirable feature.

Having an explicit concept of a resource library should be of use there. 
I don't think Zope 3's resource infrastructure supplies for this 
directly, but it should be possible to supply the system with an 
alternative factory for DirectoryResource that knows about publishing 
them using Apache. Resource objects are in control of creating URLs.

megrok.resourcelibrary doesn't supply for this directly yet. Alternative 
factory support should be easy enough to add, but it'd be nice if there 
were some higher level ability to make URLs go somewhere else. Note also 
that in order to actually know which resources there are (if only to 
generate URLs), the resource library *still* needs access to the files 
in question, no matter how they are published.

If one does this, it would of course be interesting to be able to 
specify where the real resource URLs are during deployment, perhaps in 
zope.conf (which can be generated by buildout.cfg).

People are welcome to try adding in this support. The custom factory 
support is already in zc.resourcelibrary, though I left it out of 
megrok.resourcelibrary for now. It should be very easy to add it back. 
Then it'd be a matter of creating a factory that takes looks for its 
configuration information in zope.conf, looking for a section based on 
the name of the resource library.
