That seems like a good idea, except that I don't know how I could actually
implement it.  I'm creating the adapter from zpt code, so I can't use
__of__ there.  To create the adapter, I am calling the interface, so to
affect anything there, I guess I'd have to patch the __call__ method of
interfaces (which I don't want to do).  The file system code that I
currently have involved in all this is the adapter itself, but I don't
know quite how to fit in the adapter.__of__(context) pattern into that
code.

I just tried this and it does indeed work (thanks).  Only problem is that
it is a bit of a security whole.  It'll do me for now, but I guess I'm
hoping some bright spark comes up with a better way of doing things in the
future.

Seems like what I really want is zope3 views to work with archetypes...


thanks all,
