Sure .. but TCP SYN port scanning was just one example. Any UDP/ICMP
(connectionless) or TCP non-established connection based triggers can be
spoofed with unicornscan as well. The only thing that isn't currently
easy to do is TCP full connection payload injection from spoofed IP's.
We're working on a way to do that though :).
