Problem with ltspinfo!!

Lately I was trying to create a shutdown/reboot module for Fl_TeacherTool. I recently talked with its developer Robert Arkiletian and realised that “ltspinfo” can be accessed by non-root users even. The shutdown/reboot module is a cool feature for fl_teachertool but would create a problem if non-root users gain access and shutdown terminals at their will. But this problem has to solved. So, I am analyzing the code of ltsp-ltspinfod and may make changes in it as required to curb this problem.
