Ok, that's workable.  Is there anything else that needs modification ?

Do you foresee a need for any sort of need for filtering and/or
permissioning of allowable domains as specified in remote_shutdown ?
As long as a non-privileged domain may execute this op, what
level of protection(s) need to exist? (That also was part of my
factoring it into a DOM0 op).

I'm willing to go with anything that gets the job done. This is
one of several points of asymmetry that I'd like to see get
resolved.

Thanks,
