|+1 Rich... We have a hard enough time coming to consensus on seemingly easy things. Lets first build a bridge that solves the issues we know with the current idioms and then lets gain massive adoption. Once we have those two things, we can look at other things.|
Lets not put the freeways before the horse and buggy, or even lets not put the cart before the horse. Or more in line of where we really are at, lets first figure out how to ride and tame a horse.

"Without cryptography vihv vivc ce xhrnrw, however, the only thing that can not be unscrambled is an egg."
I agree completely. Just because something (like asset information) is important and could be helpful in understanding the potential impact of a threat doesn’t mean that STIX or any component of CTI needs to define that information model. We need to keep a laser-like focus on Cyber Threat and build bridges to other communities that are looking at asset, configuration or vulnerability information.
I am 100% behind giving us the ability to communicate asset information. Just not sure it should be in STIX, or OASIS CTI for that matter. If we can do this at a higher level than CTI, then we can use the same asset standard for vulnerability, compliance, and threats. We could even use it outside of the information security space. I say we continue using exploit target until we can figure out how to get STIX out of the asset business.
ExploitTarget only represents where the "pointy end" of the stick is pointed (attack surface/vulnerability), not the organization or assets behind same. Some of us share the view that there needs to be a top level object that represents the Victim(s) and their Assets.
Wouldn't an asset just be linked using the already existing facility of @idref on ExploitTarget?
Not sure something new needs to be created...

If you don't properly manage your Assets in cybersecurity: you will FAIL.
Information obtained from the data that you will manipulate and
exchange need to be linked to your Assets, the Assets of others
(Supply Chain or Adversaries).
So -again-, I invite you to look at http://scap.nist.gov/specifications/ai/
NB: While not perfect, and I can comment further with pleasure on
where/why, the Asset concept/construct or relationships (i.e. through
GUIDs) is, imho, NEEDED.
PS: I will try to put effort on documenting where the current model(s)
are currently weak regarding this domain
