Should you wish to develop on this, I would look at the com branch in 

git://git.samba.org/jelmer/samba.git 

and the wmi branch in

git://git.samba.org/jelmer/samba4.git

But I don't know the status more than that.  Jelmer can perhaps
elaborate on the status of that code, and what needs to be done before
it can be merged.
