It does have an option to push some settings, DHCP-style, to a
connecting client.  I think the windows client would simply replace the
existing dns settings with the pushed settings for the duration of the
connection; *nix clients will do nothing with the information unless you
add a custom script to process them, requiring more work but offering
much more flexibility, particularly if the client system is running
something like dnsmasq.
