If one added logic to create a new class, that demuxed on IP addresses, it could be done. However, both the ARP implementation and IP fragment reassembly would have to be in the Packet Driver itself, which makes it somewhat bulky, and you'd have to remove the current IP/ARP in the stacks that used it. Because the people who want two TCP/IP stacks under the PDS are usually after the union of the feature sets of two freeware packages, and unwilling to do major surgery on them, I don't know of anyone who has done this particular hack.
