Indeed it does; thanks.

I had thought that the OpenSolaris distribution was primarily build
from packages produced during Nevada WOS construction.  How could
something like this be part of OpenSolaris but not Nevada?

(Perhaps you mean that this ARC case is related to that unintegrated
OpenSolaris project.  If so, then ok.  If not, then please explain.)

If this is a new driver, then please explain how Least Privilege is
applied to it.

If it's a new socket type, then does it use the Volo interfaces?  If
not, then why not?

Does it work in non-global zones?

Is there an on-the-wire protocol involved here?  If so, then what is
it?  How is it secured?  Have you reviewed the security best practices
document?

Agreed.  It should go there even if user applications don't link
against it.

What does use this?  Is there something in the system that links
against this library?  If not, then how do you know that it's
functional?  If there is, then can you cite the ARC for that other
project (or projects)?

Where is that installed?  What does it do?

Also agreed.

Are those other packages part of this project (and thus need to be
described here) or they part of some other project?
