This might sound weird but there's an explanation for my question: I want to write something to impress a potential recruiter, and I want (to strenghten my skills) to create a program which should communicate with kernel mode driver(s).

I'm not starting from a goal and trying to design the system to achieve it, I'm doing the opposite: designing the system and trying to justify it with a meaningful goal.

So here comes the question: what could a kernel mode driver be possibly useful to?

The answers that come to my mind right now are:

• I might want to communicate with hardware (not really my case, it's a software project mainly)
• I might want to mess around with the OS (security/hooking?)
• ??

I need some other examples like those
