In a software development course about reverse-engineering, the students
are given the ability to execute a program written by their teacher, and
have to write themselve a program that, taken as a black box, gives
identical output as the master program with the same input. The students
must have no way to debug the program, as the course if focused on I/O
analysis, not disassembly or source code analysis.

As the program needs significant CPU usage and the teacher has not
enough CPU quota on the faculty's system to give it away to it's many
students, the program cannot run as an advertised service in the
teacher's session, but instead has to be run with CPU usage of each
student.

For the same reason applied to the faculty or each student, the program
cannot run as an advertised service with CPU quota given especially by
the faculty or taken from the students collectively.

Pedagogically,
Nowhere man
