How do you use "the driver" now? Are you saying "driver" just in the loose sense of any software
that lets you use some hardware in some way? Or do you really mean "driver" as in developed using
DDK or equivalent and put in C:\WINNT\system32\drivers\whizzomatcard.sys? Or a privileged app?

Why do you think you want to do that? (I'm not suggesting it's a bad idea, I'm just wondering
what leads you to think you may need to do that). How do you currently operate, and how do
you hope to operate, at the user interface level?
