Maybe a local call to NM is the right approach.  I believe there already 
is a call to map xid<->slicename.  So the basic scaffolding to 
communicate with NM from a slice exists, and presumable this could be 
extended to include a slicename->keys call.  However, you'd have to do 
this periodically to check whether users have been added/deleted from a 
slice.  Polling NM in such a way seems suboptimal.

We used to automount .ssh into /vservers/$slice/home/$slice/.ssh.  Not 
sure why we got rid of it, but I suspect its because we couldn't get it 
to work reliably for some reason. Will dig further.
