Yes, that's right.

The configuration that I used for the GNU Radio transceiver can be found 
in the apps/nic.sh script.

It's not totally trivial to setup, you should have a rough idea about 
networking, MAC addresses, and ARP. Because on the other laptop you have 
to open an ad hoc network, add corresponding static ARP entries for the 
MAC configured for the GNU Radio transceiver, and set an IP in the same 
subnet as the GNU Radio transceivers TUN/TAP interface.

Best,
Bastian
