This will never be done, apart from the DMCA it would require a new driver for each new build of 
every copy protection system in the world

This is what I'm doing, the safedisc 1 driver works quite well with it, some ring 0 emulation is 
needed but that also works quite well and isn't much of an issue.

This would be a real pain as it would mean implementing the windows binary driver interface in the 
kernel, it would also not be very portable.
