I believe this is just a matter of contrib agreements being sorted out 
(Hanno?). I guess I need to get mine sorted out as well if I'm going to 
keep working on this when it moves... :-/

Workingenv made it more complex than it needed to be (or buildout did, 
depending on which perspective you look at it from). I believe Hanno 
wanted to rescue the recipe in case others found it useful, but it's not 
used for now.

I would tend to agree, especially since buildout has a tendency to 
delete things in parts/ in any case (or rather, recipes do).

I don't think it'd be hard to make such a script (perhaps more difficult 
to make it be cross-platform, we really need a champion for all this on 
the windows platform!).

It'd be trivial to change the z2c.recipe.zope2filestorage recipe to use 
a different directory. We probably need another "top level" directory 
though, because the part name is used as the directory name. Again, we 
just need a steer on what's recommended practice. For example, we could 
use ${buildout_home}/var/${part_name}...
