Sir, you get an A in my book just for the effort!
I've been looking for a way to get a small guitar recording studio going at home, and I got so frustrated with Cubase messing with my audio card that I sort of "gave up". Nobody writes low latency drivers for Windows, in fact, they've seem to have given up on real time recording. (Disclaimer: I'm still on Vista)
I will definitely be giving this a try as soon as I get home!
