Does anyone have a solution on how to handle the 'google_product_category' field that google base is going to require? I've tried adding it as a feature but you can't export feature fields independently.
I've seen where some have added fields to the db and then modified php files to include the new fields. Would really like not to do that.
We sell an addon product (XML Data Feeds) that handles it correctly and allows you to import all the Google Categories as a selectable feature. Docs are at:

and product details are at:
http://www.ez-ms.com/addonproducts/xml-data-feeds.html
It does not modify any database fields nor does it modify any other distributed code (templates or php)
It will also generate Yahoo style objinfo.xml data files as well that can be used by some other shopping integrators.
