I hope this would be very short lived.  One of Zope's major problems is that
there are all sorts of cool little scripts with certain names and special
properties you can set that suddenly (and sometimes accidentally) enable
wondrous magical behavior.  It's bad design, in my opinion, to rely too much
on them.  Like the "Scriptable Type Information" (I don't even know how to
use those), something like this should only be used to augment behavior and
handle cases that can't be caught by the default framework and
configurations.  I don't think it should be used in lieu of a real feature,
because it tends to cause development of that feature to slide further back
(or never occur).

In other words, I think that we should focus on doing this ONLY if we can
get the Types Tool to handle upload types as well.
