Clarify how this differs from similar modules (or join forces)

The killswitch module provides a very similar feature to this module.

One of the 7 principles of the Drupal project is collaboration. Would you consider merging your project into that one and collaborating with it's authors?

Otherwise, it would be great if you could document on the project page what makes this module different and also link to that module so that people can make a good decision about which one to use.
