I think your biggest problem (at least at the current colinux state) 
would be the strict timing you require. Timer interrupts are more or 
less emulated now, and could not give the resolution you intend.

But you would have problems if you use DMA in same way, as that is 
controlled by windows.

A possible solution to your problem would be a sort of "linux proxy 
drivers", who would transfer messages between your application and a 
windows driver. That driver would then make the required low level work 
(using the appropriate windows mechanisms).

Hope I have helped you.
