    on machine A you have:
    NIC A 1.1.1.1
    NIC B 10.0.0.1
    on machine B you have:

    NIC A 2.2.2.2
    NIC B 10.0.0.2

    On each machine use a modification of
    /usr/share/examples/netgraph/ether.bridge

    so that one link of each bridge is set to an ng_ksocket instead of a
    real interface.
    then send messages to each or the sockets to connect to each other with UDP.

    how to do this is in /usr/share/examples/netgraph/udp.tunnel

    by combining the two you should create a tunnel between the two bridges
    which
    should result in a single bridged network.

    that should be about all you need.
