Crawler new use and crawler reorganization

Hi,
the security scanner is first of all a crawler. It could run into the pages of a drupal installation and perform multiple tasks.
The first use of it was about security, we used that to seed patterns inside a form and to find if these patterns were not checked by drupal filters. I developed it with this intent, but while developing I see that everyone could use it to run other tasks, simpy changing some lines of code. Other task could be search for other patterns (moderation?) or something other.
In this thread we could talk about its possibile future use and, if the crawler will be a new self entity, we could talk about making it a new module and reorganize all.
