ticket system (Plugin)

[Kolyok]

Ive been working on a flat file (using xml for data storage) ticket system plugin (well actually was a separate project but converting into a GS plugin was started but is was held since it was a "working-on-it-in-my-free-time" type project)
So based on the same type project one day i might finish it.
Unfortunately the majority of open source ticket systems are built with MySql (couldnt find a good flat file one) however these offer really nice features (example: osTicket)
