/etc/dhclient.conf contains:

    omapi port 7911;

Then, as root:

    # dhclient -n -w

And in another terminal:

    % netstat -an | grep -w 7911
    tcp4       0      0  *.7911                 *.* LISTEN
    % omshell
    > connect
    obj: <null>
    > new control

    obj: control
    state = 00:00:00:00
    > set state = 2
    obj: control
    state = 2
    > update
    obj: control
    state = 2

At this point, go back to the other window and notice that dhclient hs
terminated.

I haven't played much further than this yet, though.  The only other
thing I noticed is that getting a list of what objects are present
doesn't seem to be supported.  Well, I couldn't see how to do it...
