The code to do this has been written in development
branches for a while. We will try to being it over
some time in the near future. Most certainly this
will happen after we get 2.2.0 out the door.
btw...you loose the virtual server functionality in
Samba with netbios-less CIFS as there is no called name
in the TCP session request. :-(
