Hello,
Observation re 2 layer PCI:
I can name two common devices that are sold in the
tens if not hundreds of millions of units and that are 2 layer PCI boards. These
would be ethernet cards and sound cards. These cards sell for around $20. They
need to be made dirt cheap and they need to work on a very very high percentage
of motherboards to avoid a bankruptcy inducing support nightmare. And they must
work in conjunction with whatever else is plugged into the host PCI
bus.
So my conclusion is, that in the real world
you can often ( and many do ) get away with it.
I am not qualified to answer the question from an
engineering perspective but I would like to hear what others have to
say.
