Frankly, i was surprised (and taken slightly off base) by both Avi and Anthony

It's a usability and deployment non-starter.
It's only clearly inferior if you ignore every consideration against it.
It's definitely not a deployment non-starter, see the tons of daemons that
come with any Linux system. [...]
Avi, please dont put arguments into my mouth that i never made.
Sorry, that was not the intent. I meant that putting things into the
kernel have disadvantages that must be considered.
My (clearly expressed) argument was that:
_a new guest-side demon is a transparent instrumentation non-starter_
What is so hard to understand about that simple concept? Instrumentation is
good if it's as transparent as possible.
Of course lots of other features can be done via a new user-space package ...
I believe you can deploy this daemon via a (default) package, without
any hassle to users.
