Looking for a good QNX RTOS project

I am looking for a good topic of school project on QNX. Any suggestion? I would like to work on something such like to expand the current QNX function of memory protection, task scheduling or anything that is OS related. The workload of the project is better about 50 hours.
Your suggestion will be highly appreciated!

Probably you can implement the file system using the QNX Resourse Manager.
