I have been meaning to write this email for a while now, just to let
everyone know we're working on a couple more patches related to VM
introspection. They are not as big as our initial ones, but they do
bring in new functionality.

Răzvan Cojocaru will post a series based on Tamas' changes, as soon as
it stabilizes some more or (even better) gets merged. I'll let him
choose the right moment.

I will also pick up some of my [oldish] patches with reviews from Andrew
and Ian and also try to tackle some of the x86 emulator challenges
that we talked about some months ago. We've adjusted our plans and aim
for a to-the-point set of changes that allow one to built a security
solution (at least) the we envision it, in terms of isolation and
monitoring capability.
