Newbie - starting out here...

Just one comment --- I wouldn't.

The paper was published in 1997, pre-dating even WDM. Maybe I've been stuck
in an eddy of driver development, but until your query I have never seen
anything about kernel proxy's and user mode drivers, so I don't think any
major work has been done to progress the idea.

Secondly, I'm currently involved in a project that an early driver had this
"proxy" interface between a user mode element and a kernel mode element. It
broke down into 2 kernel device drivers with an emulator in user mode. The
"proxy" driver received IO packets from the interface driver and passed them
down to the user mode component that emulated the eventual hardware. While
it's nice to know there is an academic paper supporting that method, it was
a genuinely bastardized system, slower than molasses, a pain in the ass to
maintain, and dropped as soon as the hardware was stable enough to allow
properly written bus and interface drivers.
