Not unless one has manually created a bridge.  Trying on a machine without
a bridge, I saw no option to use one. 

In addition, playing with this a bit more, I'm finding it to have poorer
graphics than VBox on  a couple of Linux desktops (Lubuntu), and it also
seems that it doesn't see Mod4.  I vaguely remember that being the case
over 6 years ago, and actually contributing a patch to the FreeBSD port
that fixed it.  (Which was just a diff file to the BSD port Makefile).

I did try using spice, but that just gave me a black screen.  Note that I
haven't put any serious effort into any of this--I'm mostly playing with it
as a platform for a few server type installs, however, it does seem that
the other two give the casual user a better out of the box experience.
