Since there are far too many modules implementing partial functionality of this module, and the slow uptake (~30 users or 0.005% of Drupal sites), I have decided to declare the end of the road for rolekeys.
Here are some alternatives
To assign a role on registration try
To allow a user to choose a role on registration
To provide a role using a key during registration
Memberships (not covered by rolekeys!)
To allow role assignment via "My account" area
Hopefully someone will be able to unify this mess.
