uc_premium_access

Using Ubercart product features, this will allow you to grant premium access to specific nodes for specific users when they purchase a specific product.

This is basically just like uc_node_access, except instead of using node access, it uses premium_content to control access. The main difference is that the content will still appear in lists and the teasers will display - but users will be prompted to purchase something when trying to view the full node.
