Since the ball has already started to roll on this, I'd like to

other protocols such as CDP or EDP can be added in). The current

Huzzah! Awesome work, Jason.
I was reading over the Operation document and the paragraph describing
what will populate the System Description TLV and a thought occurred
to me.
One of the components you're using to populate this TLV is SI_PLATFORM
from sysinfo. On SPARC boxen, this will produce a string akin to
"SUNW,Ultra-4" or "SUNW,Sun_Fire_T200" and so on. However, on x86,
this will always be "i386". I think that can be improved.
You may want to consider hooking into libsmbios on x86 to gain use of
the SMB_TYPE_SYSTEM array which contains a product string not too
dissimilar than what you'd get with SI_PLATFORM on Sun SPARC boxes.
For example, this could produce "Sun Fire X4140" or "PowerEdge 1950"
and so on, and be a bit more informative than the generic and rather
vague "i386" that you'd normally get on x86 using SI_PLATFORM.
Peruse the output of smbios(1M) if you think anything from a x86 box's
SMBIOS might be useful. libsmbios is where prtdiag(1M) on x86 boxes
gets its output.
