Quick note I have WCVP installed on multisite on one site but not network activated. Its work well, however being able to share products across the network would be awesome.
I think it might be possible to create an individual store rss feed by constructing the URL.
The URL shown here shows all the products that have the taxonomy category of photography. replacing “product_cat” with The “Vendor” taxonomy however will not work.
As category is stored as “product_cat”, is the vendor taxonomy stored as something else in the database file?
