Yeah, but I think that's the reason that it might not be a good 
candidate for this use-case.

We need a *simple* interface that we can convince everyone to install by 
default and run in their guests.  It needs to be flexible enough that we 
can do lots of fun things but simple enough that a reasonable person can 
audit the code in a short period of time.

It will never replace something as sophisticated as guestfs but that's 
not it's point.  It's point is to let you do simple things like execute 
a command in the guest or peek at /proc/meminfo.  You don't need 500k 
LOCs for that.
