Sounds like a simple device driver would handle this.

Could this be done by setting a timeout which you keep rescheduling?

Note that the standard clock tick on linux has 10ms resolution - i.e. 100Hz.
You might want to increase this to 1000Hz (i.e. 1ms resolution). I have read
of people doing this in this list.

No, its not difficult at all - its very easy. There is a learning curve 
though, just
like anything. Cheers!
