Just seeing the words "remote factory diagnostic mechanism" makes me
cringe...

Yeah, and this is exactly why.

But, also,

   Because networking cards have direct access to the computer's memory,

that's an indication you're using a busted architecture - and this is
why.  Sane machines have an MMU between the bus and main memory.  The
VAX did this back in the '70s and '80s; the SPARC did it in at least
some of its incarnations.  Apparently computer designers are another
group that doesn't learn from history (not that that's a *surprise*,
exactly, but it's certainly disappointing).

More reasons - as if we needed them - to avoid running peecees.
