There isn't any 'module' that I am aware of where someone has already adapted the starter kit to be a module that would reside within DNN and utilize its features such as its user data, etc. I see a posting on here where someone has started to undertake the task so you might want to check with them on their progress and if they are going to make it available to others for use.
I have thought along the lines of doing something like an issue tracking system as a module for DNN and I do have some initial designs of my own that are getting refined as I have time and as I work on developing an initial very basic module for DNN to get used to developing within the DNN framework. I don't have a timetable yet on when I'll really gear up working on it and I have my own ideas for design that are somewhat different than the Issue Tracker Starter Kit. But I don't plan on just taking the starter kit and making it into a DNN module as I'd rather come up with my own system.
Hope this helps.
