I'm sorry, but clearly Nate and I have a quite different oppinion
than you do here.

Please notice that code can be "very useful and correctly working"
and still be a royal mess.  Several major projects I've worked on
would be classified in that category.  For all practical purposes
the Danish Tax law fits that description too.

The main objection from my side is that the PAO code is prototype
quality.

The secondary objection from my side is that we need a general (as
in:  pccard & cardbus & docking station & mini-pci & hot-plug-pci
&c &c) framework for dealing with devices with dynamic precense.
The PAO code doesn't provide anything even close to that, but does
provide some experience with some of the low-level pccard cases.

As I said in my previous email on the topic: everybody should grab
hold of, and read "The Mythical Man-Month" by Frederick P. Brooks.
