[Zope-CMF] GenericSetup: one object -> mulitple files

i've been doing a bit of Plone-related hacking around in GenericSetup
recently, and have hit a bit of a snag because the current export mechanism
seems to be pretty tightly married to the idea that a single object in the
ZODB is going to only produce a single file in the exported profile.
this is not always the case, however; consider the case of page templates and
python scripts in the skins that often have accompanying .metadata files. in
the case of CMFFormController, this is particularly important, because the
.metadata files contain validation and traversal information that is integral
to the behaviour of the exported object.
the export behaviour ultimately comes down to 'name', 'body', and 'mime_type'
attributes returned by the export adapter. my first impulse is to add support
(in the GenericSetup.utils.exportObjects function) for these values to be
returned as a tuple; if this is so, context.writeDataFile would be called once
for each set of values.
even better, i think, would be to have the exporter return some sort of data
payload object that could contain all of the data for any number of files that
might need to be created. this would allow for more future flexibility, as well.
any thoughts on these suggestions? other ideas on this problem?
