Grant customers access to items like Nodes and CCK fields, Taxonomy, Roles etc. on your site when they purchase specified Ubercart products. Access can be configured to start immediately, after a fixed period from purchase, or on a preset date, and it can be given either for indefinite time, until a preset date or for a limited period based on the feature's settings.
Currently it has nodes and CCK fields handler that uses ACL and Content Access modules.
With future addition of more handler modules, it can grant access to other items (i.e. Taxonomy, Roles).
