But why is this project announced at NetBSD Projects page?

I've got some questions on this project:
What kind of real-time support it is supposed to be:
    - hard- or soft-real-time
    - "kernel-native" or an extension (for example, something like RTLinux
or Venturcom RTX for Windows XP)
what kind of tasks should be supported by scheduler:
    - preemptive or non-preemptive
    - dependent or independent

Or all this decisions are up to the student?
