Research tool for categorizing Drupal site content

This semester I've been involved in a research project at BYU studying the effects of using web2.0 tools powered by Drupal in the classroom (See http://isyscore.byu.edu/drupal). Now that our first semester with our pilot site is coming to a close, we're moving into the data gathering / analysis phase of research. To aid our research I've written a tool which let's an research easily categorize content created on a Drupal site.

See attached screenshots for more detail but here's a basic description. The module ties into the taxonomy module. The research goes to a node and reads the content then categorizes the content using categories/terms previously defined. Upon clicking submit, the research is automatically redirected the next node on the site that has not yet been categorized.

I'm releasing the code "as is". It hasn't been extensively tested so most likely has many bugs still. My real motivation for releasing the code is to see if there's enough interest to justify my continuing to work on it and to release it as a project.

So would anyone else have a need for a tool like this? Are there other possible use cases?

btw, change the name of the attached module to research_tools.tar.gz to uncompress. Why can't I attach an tar.gz file here???
