Sure, but it's of limited utility in the absence of vlans.  A typical 
thing to do with -net socket would be to launch one instance of qemu 
with -net user, -net socket, and -net nic.  Another qemu would be 
launched with -net socket and -net nic connected to the previous 
instance.  Now you've got a working virtual network with external access.

-netdev socket alone won't get you this.
