Before I got busy with an important project I looked at Woocommerce plugin support, currently you can set widgets to parts of Woocommerce which create unique WordPress Posts/Pages/Custom Taxonomies etc… but not for Woocommerce custom content (individual products).
You’ll find the options under each widget:
Custom Post Types +/-
Products
Custom Post Type Archives +/-
Products Archive
Custom Taxonomy Archives +/-
Product categories
Product tags
Product shipping classes
Product color
So those sections of a site that’s created by Woocommerce can have widgets displayed/hidden.
Woocommerce doesn’t create a standard WordPress Post or Page for individual Woocommerce products, Woocommerce products are similar to WordPress comments so there’s no easy way to select a specific Woocommerce product to show/hide widgets on.
To add full Woocommerce widget logic support I’d have to do what I did with BuddyPress and BBPress, try to find specific Woocommerce conditionals. It’s on the wish list for a future update, but no time scale.
